"You're right, I better." Steve huffs good naturedly and claps the back of Matts hand when he pats Steve on the shoulder. "I'm not nearly drunk enough to be straying into kissing random folks territory."

Matt is hardly random folks but that just makes it more weird in Steve's mind. This is the sort of behavior that got you beat or worse when he's from. And that's not even touching the 'dating Verity' portion of the weird. Speaking of...

"Hope he's better for you, he just sat there. I'd demand flowers for this if I were you, Verity."
