Is there a character you wished got more time to be shown in CC? Like, given more of a personality or being a bit relevant?
Oh, absolutely. There are MANY characters I wish got more screentime/had more relevance/had more of a personality! In fact, I'll list one character per game that falls into this category (limiting myself to just one, otherwise this would be a LONG list!)
Season 1: Grimsborough, Morgan Goodwin
CC so rarely explores the effects of being related to a murderer, especially a serial killer, so it was super fascinating to see Tess' younger sister, her relationship with Tess, and the consequences of Tess' actions on Morgan, because it is absolutely true that families of murderers/serial killers get harassed, like Morgan and her family were experiencing. I would've loved to see Morgan in her normal life, explore her complex relationship with her sister, who, despite her crimes, I do think cared for Morgan. Wished Morgan appeared in The Conspiracy.
Season 2: Pacific Bay, Heather Valentine
Why on earth does she appear so little? She has an awesome design, a lovely relationship with Hannah, and also disappears halfway through the game, not even being mentioned after White Peaks. What was all that build up for? Heather is introduced and seems to have relevance/build up to being an important character, but abruptly gets kicked out the game. A shame that happened to one of the members of the franchise's first main, queer couple. She should've been a recurring character.
Season 3: Save the World, Michelle Zuria
I'll be honest, s3 is my least favorite game in the series, but even I am supremely irritated by how stupid her death is. She gets, generously, three districts to shine, then she's killed by a suspect who's never appeared before (hate it when that happens in a district finale, it seems like such a cop-out), because this intelligent and cunning woman decided to wander off on her own in the birthplace of SOMBRA, with no backup, without telling anyone...and if I remember correctly, we don't even learn why she went off on her own! Screw that. If you're going to kill off a character, you should NEVER make them stupid to contrive the narrative to fit killing them off. That's a huge pet peeve of mine. Michelle deserved better.
Season 4: Mysteries of the Past, Veronica Rochester
I was originally going to put Clarissa Rochester here, but stopped, because I still felt like we learned a fair bit about her in her case. Same with Lissa Avery, another person I considered (Lissa, feel free to direct Samson's calls to me...). But I ultimately decided on Veronica, because it fells like we know nothing about her! There's a lot of interesting potential to her. She was only 19 when she gave birth to Archie, and she lives in a place with lots of factory fumes that wouldn't be good for an asthmatic, and doesn't seem to be very involved in her son's life. She says in Civil Blood that Archie's studying to take over her business, but that doesn't seem to be true, even if he briefly worked with her when she returned. Was she lying? Unaware he was getting a law degree? She initially appears apathetic and controlled, but that mask can easily skip into anger, irritation, frustration. Did she know her husband cheated on her and was violent to their son? Did she care? And most of all, where did she go?! Did she ever learn of Archie's death? Is she dead? Did Malcolm or Horatio kill her? If so, why? Did she stage her own disappearance? How? Why? All answers I wish we had gotten.
Season 5: The Conspiracy, Julia Brine
This is probably the most obvious pick. I won't go into too much detail as I made a post about this a while ago here, but she's the only Ad Astra member not considered a recurring character. When you have such little content the only thing I remember about you is you're a germaphobe, CEO, tried to spread evil corn, gassed a kid and his dad, has a crush on a violent misogynist, took a grenade to the face after agreeing to fight against a greater evil (without being directly talked to, unlike Joe and Rozetta), and, when I showed a picture of her using her power to a friend of mine not in CC and they said it looked like she was ripping the biggest fart...there's something wrong, especially for someone meant to be one of the main antagonists of the game.
Season 6: Travel in Time, Nebet
Now, this might be a surprise, since Nebet is by far the best and most developed character in the game. But that's the thing. She so blows everyone else out of the water to the point that I don't care about anyone else, I want to know more about her. More specifically, a detailed breakdown of what happened when she was in exile that made her realize how wrong her family was, how they, including her, needed to be stopped, lethally so, how she was at her happiest when she was with the main characters. I'd read a book just about her in exile.
Season 7: Supernatural Investigations, Luke Fernandez
Out of all of the main characters in this game, I always felt like he was the least developed. All the other main characters either have several cases/have an arc dedicated to them (ex: Gwen and her family, Hope and her guardian, plus the entire end of the game, Priya has an adorable, game-long romance with Zander, etc). But Luke doesn't have as strong of a backstory/detailed backstory as the others, doesn't have a lot of relevance to the story/game, and doesn't have an interesting/compelling relationship with any other characters. Luke is just kinda...there, which is a shame, because with one exception, I actually like all the main characters in s7.
Season 8: City of Romance, Lea Bonnet
I was originally going to say Cody James since he's severely underutilized after his interesting story in the first district (and okay story in the second), but I picked Lea because I defy anyone to name a single thing she ever did in the game
That was super fun to write, thank you for the ask!
