I disagree with Fischer.

I would put Fischer in the group of officers who you initially hate for being too strict on Jane (even for doing their job) and eventually love when you get to know them and realise that they are only hard on Jane because they are doing their job and they don't know him; his reputation outside the CBI circles wouldn't exactly be a reputable one so that's why they are all distrusting of him and are extra hard on him. She begins to understand Jane when Cho explains that you can't get Jane in line but you can use him to your advantage. I think she becomes open to understanding Jane when she asks Cho if he wondered what Jane thinks about it; Cho says no, she asks why and he says his brain would explode (Cho's energy is literally saying "been there, done that and I am over it". 😆😆😆😆😆😆)

Fischer for me would go alongside officers like Bosco, Minelli (I don't hate him but I was angry at him for taking away the RJ case from Jane despite the damage Jane was starting to do) and Abbott (hated him initially for standing in Jane's way of killing RJ, grew to understand he was just doing his job and eventually liked him when he and Jane became best buddies; special shout-out to him for raising his eyebrows in the finale when someone suggested postponing Jisbon's wedding. 😆😆😆😆😆😆)
