The majority of last season was a dark, dark time for Sasha. Not only did she lose her love interest as poor Bob did the whole tainted meat angle from the comic books, she then lost brother Tyreese in what was one of Season 5s better episodes. After those events, she went a little off the rails, seemingly embracing her own death wish and becoming a master sniper as she set about unleashing her rage on any and all walkers. Whilst she wasnt Carol level unhinged, Sasha was certainly getting there. And so, it was a little strange to see her now acting as the voice of reason to Abraham Ford when he has his own bloodlust issues, be it people or walkers. It seems that maybe the PTSD of sorts that was affecting Sasha previously has now started to wane a little, leading to her being the cool head amongst this duo.
