But nobody cares about the sister. Bet most people don't even recall the character. I doubt she will even be in it. I kind of wonder if even Awkwafina will be in it. I think it's going to be more of "Doctor Strange" situation were all the supporting cast from the first movie is dumped down to maybe a cameo at best. Then just take the character into a brand new situation. They kind of did that also with Thor in Thor 3. In Thor 3 all of sudden he is hanging with The Hulk, Valkyrie and Korg and of course still Loki.
They also did "What if" together.
Marvel is pissing about.
