David came from a place where heroes and spies and extreme speed and wings were a thing. He had a definite advantage of not being bothered by what he did know, and unlikely to be bothered by what he didn't.

"I am sort of chilled and find there isn't much quite so good as a kiss to warm me," he offered with a smile, and of course as permission. Even leans in to meet the guy part way.

What can he say, he's always a sucker for a kiss. Especially when there are weird circumstances. Truly one must wonder about his luck. Or maybe he just had a weird secondary mutant power.
