Are you talking about Trish here? Because, much as I HATE how they wrote Trish this season, I do think they weren't being out of character. They set everything that Trish did in this season up in the last season - her love of the spotlight, her desire to be the savior rather than the saved, her addiction, her insistence on being included. It's all there (since I did a rewatch of s1 immediately before bingeing s2).
