Hello! Yeah, I can imagine that Wanda would find him a little hard to be around especially now because he's recently gotten his memories back after aging back up following the kiddo plot. He's got most of the memories in there, but they're just jumbled out of order for now since his sense of time isn't the greatest.
Thor will of course be okay with Wanda for the most part. He gets that the twins were a little or a lot misguided and confused when it came to the Ultron business. He'll be on the lookout for her and her power, but he doesn't really hold it against her.
