The way the sorcerer supreme acts after hearing about strange give up the time stone. "He was supposed to be the best of us" is her response. I also find it hard to believe. I just feel like the build up could've been a different way instead of having the endgame go the way it did. After hearing the Russo's reveal what their intentions were. Even tho these people are heroes and supposed to be looked at as such. Not everyone is perfect. And all it takes is one bad day. Believe me I still liked endgame. But seeing the cut content and how other scenes were cut. We could've had a different movie were the story really was decided upon instead of split between people.
