The Jean storyline is really annoying. I actually think it's quite well done, as in, the change in personality is subtle enough that it's only obvious if you know her. But I have always hated Jean, I hate any storyline where she is the main character. I hope she leaves after this, maybe she could run off with Mick Carter.
Ben as a vigilante is completely unrealistic, he was frozen with fear due to a few bangs at the start of the episode but beating someone half to death by the end
also not realistic because he killed Heather and hasn't been violent since due to his serious regrets
