For the ask game, absolutely Emily Prentiss.
An obsession of mine since she first joined the BAU.
I have no shame when it comes to Prentiss
Or if you want to go old school, maybe some Shaw from POI
for the character ask game: Emily Prentiss
How I feel about this character
I really love Emily Prentiss! She's my favorite character on Criminal Minds even through my first watch of CM.
Honestly, I didn't expect to like Criminal Minds as much as I do because I'm not usually into shows that has a lot of well... gory deaths. But CM managed to walk the line and a large part of that is the main characters and the character dynamic!
Emily was one of the people that really caught my attention, I loved Elle in the first season and was so sad to see her go but then Emily entered the picture and she has such a different dynamic. And Paget Brewster is so charismatic.
It took me years to realize that she's Kathy on Friends.
All the people I ship romantically with this character
I think Emily has chemistry with everyone! (Except, funnily enough with her last boyfriend in season 15).
So, of course, I ship Emily with JJ and with Morgan.
I can see the Hotch thing but it didn't really click for me but also I can definitely see Tara/Emily too. They have similar backgrounds and instant understanding of each other.
Briefly, there was this frisson with Luke Alvez, but I think it fizzled because yeah she is his boss and rightly so Luke's been smitten with Penelope ever since.
My non-romantic OTP for this character
Honestly? I think it's David Rossi. Rewatching things, I like the slow build of their friendship and he is not quite a father figure to Emily. But enough of an authority something figure that when Rossi says stupid things like 'I forbid you', it triggers Emily's rebellious hindbrain.
Tara also occupies this place, I think it's partly due to them sharing a similar background and she wasn't there the first time for the Doyle stuff so Emily can feel okay bouncing off ideas with her. She wasn't a teammate from before so she can also properly establish that she's the boss. Not that her friends don't accept her team lead but sometimes I think Emily just wants a clean slate.
My unpopular opinion about this character
Unpopular even to myself! But I think now, after everything she's been through, what her friends have been through, Emily needed that time away from the BAU.
If she stayed in immediately after Ian Doyle thing and kept seeing the same thing, she would have burned out. Emily had to find her footing outside of the BAU.
One thing I wish would happen / had happened with this character in canon.
I wish they recast the actress for Elizabeth Prentiss, I know the OG actress retired doesn't mean we shouldn't at least see Emily interact with her mother again. Emily's in Washington DC, don't tell me her mother wouldn't visit one time and make Emily's life a nightmare by requiring her to attend some state dinner with her, even if Emily is in her 50s she still reverts back to Classic Emily.
I wish that the show would acknowledge Emily actually would have more political connections because *waves hand* Ambassador Prentiss. But also, she would have built her own. Emily was head of London's Interpol branch! Or at least, I think the counterterrorism part of Interpol... Clyde's job was really hazy and the show never really clarified what Emily did.
I wish the show delved more into the fact that Hotch knew Emily while she was just getting over her rebellious teen phase. He must have some amusing stories about Emily that I wish he shared with the team.
I wish the show would lean into some spy thriller episodes now that Criminal Minds is now on streaming. Counter-terrorism still deals with Human behavior after all.
There was that one Vampire episode with Gavin Rossdale as a guest star and the show didn't delve into the Goth subculture even though they lampshaded Emily's past. Like, she's a decades out of that subculture but she's still a goth at heart (look at all her clothes), she could at least share some insight.
I wish the show didn't forget that Emily is actually better than Reid at both chess and poker.
Criminal Minds writers admit that they don't really plan things ahead of time but there are some moments I can point to now in hindsight that works to foreshadow Emily being both a great spy/undercover agent and team leader.
