That scene with Aneska at the end of the season was horrifying.
I feel bad for all parties involved there. Except her of course since she's doing something wrong to people who have only been nice to her. I hope they figure this out soon and it doesn't drag on half the season. It's a soap trope but it's one that I've never liked.
OUAT has done something similar several times and it was never addressed. First with Graham and later Rumple then with Robin. It was wrong every single time and the show didn't really address how horrifying it was--for the characters or the audience. I hope JtV does a better job with the fallout. And I hope they don't make it seem like Raf was wrong when he wasn't thinking clearly nor did he have any reason to think Aneska would do something like that. I don't think it'll take him long to realize she isn't Petra though. He's a pretty smart guy and he knows Petra better than anyone else. I think he'll see right through Aneska's act.
