She grinned and met his eyes. "I like you too, Peter Parker. So don't be nervous. We're just two geeks kissing to the intro cinematic of Phantom Pain. Nothing to be nervous about." She was actually vaguely nervous that Tippy might not be able to get her other three squirrels to give them some privacy, but that wasn't too big a deal. They'd seen people kissing before.
When she kissed him again it was more gentle and inquisitive, trying to soothe him with actions instead of just words.
