Matt shallows, unsure of why he's doing this, exactly. It's not really Christmas. He's not a fan of the holidays, and likes them even less after what happened this past Christmas with Tyler's mother and all those hybrids Tyler busted his ass helping to break their sire bonds with Klaus. And this is the guy's sister. If he's going to give her something, he can go out and grab a couple things, not go for a grand gesture like this, especially when he's still so unsure of what he wants out of this. His mind isn't made up yet, but...
"We're not standing on a bomb, and I'm not drunk off my ass." His hands lift, fingertips grazing her cheeks. "Least I can do after all you've done for me -- saving April's life, helping me graduate from high school, dealing with that bomb... I can do this the right way."
He kisses her -- gently, slowly, without anything beyond wanting to give her a proper kiss influencing his actions.
