I mean, I don't hate her but I certainly do not like her much. Someone else explained this better but here it goes. Jemma had us believe upon her return that she had suffered some unimaginable horror during her absence. She gave Fitz, who literally spent every breathing second to rescue her, the silent treatment under the guise of "PTSD". She threw a fit, made him feel as if he had done something wrong, only to finally tell him what actually happened. And what if we find out is that she DIDNT suffer, or at least not to the extent that merits how horribly she treated Fitz. Hell, where was the trauma in all this? She had a hunky astronaut for a company, while working towards a possible solution to her journey back while shacking up with her new guy. A dude she had just met when she clearly knew how Fitz felt about her. What makes it even more repulsive is how she kept mentioning how he's her "best friend", and how much she relied on him to be rescued, all the while banging Will. How pathetic does that make Fitz in the face of all this? He can't be mad at her; she was in a dire situation. She's also not technically dating him. So here he is, stuck between two rocks; unable to express disgust and forced to rescue her new lover, a dude who literally made Fitz's months, years of dedication to Jemma (remember when he suffered brain damage for her?) look like a pathetic waste of time, like that one shy kid in high school who would do homeworks for the girl and take notes for her for months to get her attention, only to see her snatched up by the school quarterback in a matter of a day. Hell, he probably doesn't even know her last name. In short, she made a fool out of Fitz, and trapped in the worst situation possible. You wanna save Will so bad? Go do it yourself. To expect or want Fitz to help is insanely disrespectful.

But like I said, I don't hate her. Her life, do whatever she wants. But I will lose all respect for Fitz if he still goes for her after all this.
