Gamora and Sam
Passing through on his way to the library, Sam couldn't help but stop and laugh at Gamora's face. "Yeah, those are definitely an acquired taste," he said. "But since some of us aren't blessed with superior genetics, we do what we have to do."
He hadn't actually met her yet, so he figured that he should also introduce himself, especially after laughing at her. "Sam Wilson. Falcon," he said, holding out his hand to shake.
