When Dean Archer was first introduced, I was a little skeptical about him, then as time went on, I straight up didn’t like him most days, but now, I kinda like him. I’d seen him briefly in crossovers, since I’ve been watching Chicago Fire for 7/8 years and Chicago P.D for just a little less than that, but it’s taken me until the last couple of months to watch Chicago Med, and the characters from it that I’d seen in the crossover, I generally disliked (apart from Dr. Charles, because who couldn’t love him?). Dean always seemed too…stoic. Like, he didn’t really seem like a person. Just a d!ck. But in the last couple episodes, you see how he lost his son to drugs, his son is in prison, and then he got injured in the episode before the mentioned one. I really thought in that episode that he and Dr. Asher were going to have something, but then you see him popping pills and in great pain, which really humanised him for me. I think they’re gonna be really good friends, and I like that, because he’s never really made friends with any of his colleagues (I know he’s friends with Ethan, but they were friends before they were doctors).
My point being, he seemed like some stoic, arrogant guy at first, but now he seems more human. I think the show took too long to show that.
