Wanda lost more than her confidence. They all lost a bit more than just what's on here. Steve lost some of the people he called family. Natasha is forced to be a government pawn again. Wanda lost her freedom, her confidence, her trust in people.
Can we just talk about the end of the credits for Winter Soldier? The Winter Soldier/Bucky going to the museum, and seeing how close Steve and Him used to be, and seeing who he really was, just a heartbreaking scene!
