I think there's a chance that she'll survive. If she does not betray Zoom, she'll probably get locked up on Iron Hights because from what we've seen she's fighting the Flash.
Maybe even if she betrays Zoom, she may still escape in the big fight and, as this is the last two episodes, we know Barry is going after Zoom for real. I do think they'll let a lot of Earth 2 meta humans loose at Earth 1 so they can have a lot of vilains of the week next season without much explanation, just "oh, he's from earth 2 and got stuck on this earth on last year fight" and no further origin story is needed.....
