On Hatice’s character, I feel like she more or less was cheated of a better character arc which could’ve made her more likeable or easier to understand (almost everyone I’ve encountered who is into the series has extreme distaste for her character.) Though I don’t necessarily feel any particular form of intensity towards her character I do wish she could have been explored a bit more? I can see why she wasn’t likely due to time constraints/needing to stay consistent with plot lines but it would have been nice to see. I feel like everytime Hatice was on screen, mentioned, or involved in the plot line it was in conjunction to or in relation to Ibrahim. Even after Ibrahim was dead, Hatice’s whole storyline was just..Ibrahim. It was clear that she was emotionally unstable and dealt with attachment issues from the start of the series, likely resulting trauma from her father’s bloody reign. We’re told she was “her parent’s favorite/the spoiled one” according to her siblings, we’re hinted at some sort of past fued between her and Sah but no real context. We rarely got to see her interact with her children. It’s like we only were given tiny bits and pieces of Hatice as her own person and everything else about her just existed to string Ibrahim along. It’s quite sad..what do you think?
Eh, I absolutely adore Hatice as a character and I feel she got a very solid, well-written character arc. I'm pleased with what we got with her in the show and I think that her nuance tends to be massively overlooked.
The center of her character is not really Ibrahim, but rather the line between family and dynasty. And while that seems to be attributed with Ibrahim in the strongest way, it also channels in who Hatice is as a person and her interactions with other characters like her mother, Süleiman and Hürrem.
Hatice has always been the sultana of blood that is closest to the dynasty, but also the one that wants to detach the most from it. As you said, she had lingering trauma from her father's reign /which indeed is only hinted, to be honest, but that's the whole backstory of Selim Yavuz, what we got from his cruelty in the show was basically hints two flashbacks. We were told by Süleiman of his defining deed, we were told by Valide and Hatice that they saw his father in him, but the rest remained pretty much vague, which isn't a problem with Hatice's character. However, it may come off as a problem with SS's character, since more backstory would better explain his paranoia outside of actions of the "suspects" taken out of context, would render Mustafa's death a little more understandable and would highlight even more his character arc, for Selim Yavuz was his "Azraeel", according to him, but that is a post for another day./, but on a more personal note, she has witnessed the death her former husband, which puts her panic and fear over death in another light. Her backstory isn't that focused on, because it's not all that important for her character arc: because while Mahidevran has to get over her past and Şah Sultan tries to consistently set herself for the future, Hatice has to face the events of the present. She's an effective deconstruction of the Princess Classic trope she started up as: an innocent, fragile, kind hearted princess, no sign of trauma whatsoever who strives to create a family of her own, as a bonus. After she meets Ibrahim, she feels like she wants to be in that adventure with him, she not only falls in love with him, but he fills her with hopes and dreams for a better life. Look how when she marries him she wanted to get out of Topkapi as soon as possible and always repeated that she wanted for them to be a family, that she wanted to have piece. Even her love for Ibrahim is much more deep seated than some plain obsession that is only used as a plot device or to prop him up. She's grown with beliefs that have been a part of her life and sometimes she lets them out out of sheer ignorance, no matter how much independence she wants in her personal life. Her whole relationship with Ibrahim is a back and forth conflict between dynasty and family that is only a vector for her arc, not the entirety of it.
It's often ignored how pivotal is Hatice's relationship with Valide. The closeness she has with her, especially compared to her other sisters, shaped up all of Hatice's life long beliefs. Namely Valide is the root of Hatice's love and respect for the dynasty, being next to its female representative her entire life (see also Valide's flashbacks in E58) and witnessing the way she dealt with things, the way she ruled the harem, the way she made decisions. Even Hatice herself considered her as her role model and wanted to be like her. (she told her this in E61) It was as if Valide was a preserver of all the virtues Hatice deemed as worth having. She has a tremendous respect for her and her opinions and this is what brought her to hide her love for Ibrahim more than anything. The respect she has for the ottoman laws and the ottoman dynasty and the ways she got used to them made her to do anything but admitting SS and Valide her true feelings.
Valide is an indirect reason of Hatice's supposedly "inpartial" point of view in the harem that let her judge things more fairly. It's not that Hatice was completely unbiased in her relationships with Mahidevran and Hürrem early on, because oh no, she wasn't, Hatice always was on the dynasty's side in this war, but for her dynasty always advocated fairness and preserving piece and order. She wasn't afraid to call out whoever she thought was wrong at any time and even when her bias had completely (and honestly, rightly in many aspects) impacted her in terms of Hürrem, she wasn't afraid to admit that she was right about Firuze after all. Hatice also has a very reactive personality: she doesn't let anyone provoke her and quickly responds when she's provoked. She's not provoked only about Ibrahim, she's also provoked when it comes to both family and dynasty, overall, seeing Hürrem and Mahidevran quarrel in E11, Fatma and the concubines challenging Hürrem in E47, Mahidevran attempting to kill Hürrem's children in E55, Mihrimah defending Hürrem in E84 etc. Whenever something she cares about is opposed or attacked by someone, she would always spring into action, which is a very consistent trend of her character as a whole.
{There are many reasons why I personally find Hatice sympathetic: she's one of the most ethical characters of the show, acting as a peacekeeper wanting to keep everyone out of their struggle, she's always ready to help, she cherishes love (her wanting to marry Sadıka to Matrakcı), there are so many people she cares about outside of just Ibrahim - Mahidevran, Mustafa, Valide, her sisters and their problems impact her as well, despite of how "self-centered" she may seem at first glance. She, just like MCK Gevherhan, is so humane to everyone she interacts with, trying her very best to empathize with them. (to the point Mahidevran told her in E05 that if she keeps up worrying only about them, she will wither in this palace) Her trauma and circumstance also bring in a lot of empathy for me, because significantly little of it is her own doing, compared to other characters. We see a character that deteoriates both internally and externally often as a consequence of her simply fearing she would lose everyone she loves and that her life would be once again, filled with illnesses and death.}
[Truth be told, I don't get the Hatice hate, like AT. ALL. I don't know about you, but people I've encountered on the Internet couldn't give me a valid reason as to why they hate Hatice so much. They either reduce her to a "whiny", "crying", "spoiled" or "evil" bitch, either say they hate her because she breaks down a lot or because stood up against Hürrem for no reason, which is totally untrue, in my opinion. I genuinely haven't seen one (1) good argument as to why she deserves such ire. They mostly look at a more dimensional version of S03 Hatice and forget everything that set up S03 Hatice, or they hate Hatice exclusively because of S03, which.... eh? I would dare say that there are more reasons to hate Mahidevran than there ever were to hate Hatice (even though the hate directed at Mahidevran is, once again, for all the wrong reasons) and if someone gave me an actually good reason to hate Mahidevran, I would understand, but Hatice? Even her more questionable actions were ultimately provoked by something or someone.]
Her first traumatic experiences in the present is also connected to the kids she's lost. Yeah, giving her more time with her living children and seeing her more as a mother is the one thing I would definetly change in her writing. We didn't get enough of that and it would be a breath of fresh air. But then again, losing so many could've demotivated her and the last time she was pregnant we also had this prevailing, but understandable fear. It also just doesn't play such a big part in her deconstrustion-to-become-flanderization-in-character-development arc.
We gain a gradual, broader perspective into her a bit later in the narrative, and perhaps that eventually broken first impression would cause disappointment - Hatice could be prideful and while she wants to detach from the dynasty for her family, she values her own position and the rights that are offered with it. She could be easily offended by remarks made to startle her. She could be demanding sometimes. But that existed along with her good traits. Hatice was the most reasonable and morally unproblematic character of the main cast overall and by S01/2, that truly showed.
If we refer only to S03 Hatice, it would make a tiny bit more sense for people to not find her that sympathetic. Because while she underwent a good flanderization arc, it's still flanderization and some traits of hers seem to be more present than others in that season, especially knowing the trajectory of said arc. It may look like there isn't a sympathetic reason to do what she does, as if she's like this all of the sudden. But here's the rub: season 3 wasn't supposed to give this much context to Hatice's actions, it's the pay-off of a build-up, the peak of her arc that leads to a resolution. Season 3 wasn't supposed to repeat stuff that has already been established, all Hatice is doing there, has been set up for an entire season, if not more. We already know what's driving her, we already have the sympathetic reasons. That's why all the attention is given to her actions that bring her to tragedy, not to introspective scenes.
Back to Ibrahim's relation to Hatice's character: A common affirmation I hear is that Hatice's rift with Hürrem was caused thanks to Ibrahim and Ibrahim alone. There's so much more to it than that! While we had the scene that started the build-up and the one that ended it be about a possible/already a fact infidelity of Ibrahim's as a parallel, these are only a part of it, not it in its entirety. Keep in mind that the one thing that fully set the upcoming enmity in motion during S03 is Hürrem taking Valide's chambers. And at first Hatice wasn't about to blame Hürrem for it all when she went to tell it to his majesty (her saying to Gülfem that it doesn't matter who told her about the affair) with her claiming that Hü ruined her life only after their confrontation for Valide's chambers. And here we return to the center of Hatice's character: thing is, whether we liked it or not, Hürrem always was a threat to the dynasty in Hatice's eyes. Şah asked her the infamous question: "The dynasty or Ibrahim?" when she was asked why is Hürrem a threat in E81, but I think both are in conjunction, yet independent of each other here. Hatice values tradition just like her mother and Hürrem breaking them all would cause some kind of disturbance. She got distraught right after she was freed and married, claiming that it had to be stopped before it happened, look also how she told Afife Hatun that Hürrem had to be gotten rid of because she caused unrest in the harem! Not only Ibrahim's death, but Valide's death impacted her so much, she thought someone had to supposedly protect the dynasty for what is to come before everything goes haywire and that's what she attempted to do the entire time. In S03A personal motives clearly ran together with the apparent protection of the dynasty (I sometimes like to parallel Hatice's dynasty with Kösem's state in my head, despite that Kösem's urge to protect the state comes more with her role as a ruler and regent and measures out of necessity, while Hatice's comes from willingness to preserve balance and harmony in a more personal level.) and she considered Hürrem as a threat to everything Hatice believes in. She seems to also take on her mother's footsteps in that regard, in a way, using common for Valide methods like sending a concubine to SS etc. She considers Hürrem a threat for her own stability and well-being and that isn't limited to just Ibrahim.
Her relationship with SS is the one that is probably the most connected to Ibrahim, judging by their first more "nuanced" scene for me (him deciding to marry Ibro and Hati) and fallout (the confrontation for Ibrahim's death), but that could be also connected to what Hatice has previously experienced and genuine respect for him as a brother before all the rocky stuff happened. And interestingly, her deep resentment and then despise of him is targeted at him bringing Hürrem to their lives, not simply just killing Ibrahim, though that was also an intensely strong motivator of hers.
Hatice's bond with Mustafa is also strong even before she fell in love with Ibrahim. She also considered him "the future of the dynasty", played with him in the gardens, comforted him in tough times when she could. They didn't have as many scenes together, but the relationship added a good amount of flavor to her character.
A reason why I think Hatice's relationship with Mahidevran is so precious and criminally underrated, is that this is the relationship least centered on Ibrahim, second only to Hatice's with Valide. Their scenes early on is mostly them being there for each other and being happy with each other's moments of good time. They're very bound to each other and are very good friends that still have a dynamic relationship. The temporary S02B fallout between them has everything to do with Hatice's disappointment and disbelief of Mahidevran's own failings. She also threatened something Hatice cared about and did something she didn't expect of her. And that isn't barely noticeable, Hürrem even remarked that Mahidevran is becoming alone in E58. (oh my, I hate this scene with passion, but anyway.) After that their dynamic then remained basically intact for S03, expect that they could act more like allies than friends. But that's a given, due to the more intense events in the palace and the tonal shift of the show.
I find her dynamic with Şah fascinating due to their contrasting personalities and strained, yet loving relationship. The feud between them had enough context given to us through Beyhan's words to Şah in E83: that Hatice not only was Valide's favorite, but she apparently had the life Şah wanted to have, which explains Şah's ambition and supposed distance and secrecy well enough. More backstory would mean destroying the interesting duality in the relationship and wouldn't make Şah's motivation half as interesting and uniquely presented as it was, to be honest. Which is why I find her dynamic with Hatice way more interesting than her dynamic with Hürrem (which is good, too, but pretty generic), but that's also a post for another day. But Hatice is actually the more open person in this dynamic and the one more revealing her feelings. Şah wanted her to move on from her losses, but Hatice objects so strongly because it all has gotten to a completely personal level, with Şah trying to redecorate her castle, it would look like she's trying to change her from the outset, her as a person, which is something Hatice would never agree with. But then again, it's clearly shown that deep down Şah cares about what Hatice wants and is trying to do the best for her in her own way. And the emphasis is again put on family: they still get along and reconcile, setting their differences aside.
Many of Hatice's introspective scenes were with Gülfem and while they talked about Ibrahim many times, we could still see the amount of powerful support between them. Hatice shared everything with Gülfem, it was as if they knew everything about each other. They were each other's comfort.
She showed moral support to Beyhan, as well. That is another familial relationship that shows both casual and profound interactions. It's not there as much, but that's more because of Beyhan's limited screentime, not because of something to do with Hatice.
Even her arc with Ibrahim isn't all about him, but is also tied to the core of her character. The line between dynasty and family drives their whole fallout and if it wasn't there, the conflict between them wouldn't ever take place. Hatice ultimately forgiving Ibrahim is more about her getting out of her own dynastic outlook, which is a relevant character development of hers that happens along with her flanderization. And that plot-line is as important as the flanderization, even more so, and it pushes it forward. It was a resolution of the conflict with family and dynasty in Hatice, not exactly forgiving Ibrahim just for Ibrahim. (that is also a factor, no doubt, because she loves him and he is a part of her character, but not all her character.)
Overall, for me Hatice is a multi-faceted, amazing character that is actually very fleshed out in the span of three seasons. I don't find much issue with her writing: everything that happened with her is logical and well-explained if you look closely enough and I don't want more for her arc. It was original and outstanding for what it was, both as a character concept and a dynastic sultana of the franchise.
