If you have seen Avengers Endgame, you know how emotional it is. We lose some of our favorites. ***Spoilers Ahead!*** I don't think we've seen the last of one of them though. Black Widow can be returned. They kept saying a soul for a soul on Vormir. You must sacrifice someone you love. So if someone else sacrifices themselves for Widow, can she return? Or we still haven't seen what happened when Cap returned the Soul stone. He is gonna run into Red Skull and that won't go well. Then when he returns the stone, could that bring Natasha back? Either way, I don't think she is dead. Here is what the writers are saying about it.
