Yay, I feel happy to find a spoiler & rumor discussion too. Now when waiting the new episodes it is fun to think what might come ahead.
Sasha thing sounds like something one could assume to happen. Still so sad. I like Sasha, even still she gets so little of screen time, she is cute and funny and would have deserved a bit more happiness before being killed. I wouldn´t have minded to see Rosita going rather than her, as Rosita isn´t even smiling a lot and I wish more of the "normal" people would stay alive, not only the soldier type ones.
If she has to go, I think some happy flashback memory with Abraham would be nice.
Shell be reunited with her loved ones
