"Now remember. You have to return the stones to the exact moment you got them.Or you're gonna open up a bunch of nasty alternate realities." Bruce explained.

Steve nodded before closing the briefcase.

"Don't worry Bruce. Clip all the branches." Steve told him.

"You know, I tried. When I had the gauntlet, the stones, I really tried to bring her back." He looked at Steve. "I miss her, man."

"We all do." Ash sadly nodded.

"You know, if you want, I can come with you." Sam offered to accompany Steve into the past.

"You're a good man, Sam. This one's on me, though." Steve turned his offer down.

Steve walks over to Bucky.

"Don't do anything stupid till I get back." Steve joked.

"How can I? You're taking all the stupid with you." Bucky smirked at him.

The two hug each other.
