I wouldn't be surprised if they kill off some of BP's supporting cast. I don't think Disney had any idea that BP would be as big as it was during production of both films. Then again, Feige might have because he has good sense about when it comes to gauging how successful a property can be and he was very confident about Panther.
NO way, even if that was the original plan they're changing that shyt last minute. The BP cast is like their own avengers now and we only got to live with them for about 2 months lol
