I mean, they completely ruined Brett's storyline in every way possible and I liked her character a lot. Before she came to Chicago she had fiancee, then she dated Cruz, Otis had an eye for her and I think he still has (based on his reaction about Jimmy working with her on ambo) and also she had a fling with Roman from PD. In some interview when season 4 premiered one of the writers said that they explored a romance with Brett and Severide, but eventually decided not to go for it because it would look bad on everyone (Cruz, Severide and her) - TRUE STORY.I kind of liked the idea of Brett/Severide pairing because they are complete opposites and it would be interesting to see him settle down for once. Basically they didn't go for it because she was a good girl and they wanted to present her that way. Now they're doing EXACTLY what they said it would look bad - Brett telling Jimmy she had a thing for him since he came to the 51. What? They never showed any scenes that would indicate that. And it looks bad because Chilli was with him and she and Brett are friends. Exactly the same. This Jimmy and Brett thing is just beyond weird. Not that I don't like them as a couple it's just the way they started this whole thing. Oh shocker, he is also qualified paramedic.
And this new firefighter... She reminds me of Dawson. Not in looks but just the way she is - her character as strong, independent woman. I don't like it. It's not original at all. We already have one Gabby and she's enough.
