Sasha was a least favourite character for many fans in Season 5. Its only natural that shed be upset after losing both Tyreese and Bob, but it felt like her attitude was less sympathetic and eventually she became tedious. Now though, Sasha seems to be bouncing back from her depression. As seen in the car with Abraham in the season premiere, Sasha isnt interested in dying anymore, and it's possible that shes going to try to utilise this new energy in helping the preservation of Alexandria. It is possible that Sashas character is being groomed to take over that of Andrea in the graphic novels, as she seems to be becoming the eagle eye sniper of the town in this universe. That doesn't necessarily mean we'll see any romances between her and Rick budding any time soon, as theres not enough chemistry there, but that doesnt mean she wont be a valuable asset to the group. Keep an eye on Sasha as she becomes more involved in group activities now that shes evidently got a new lease on life.
