There's a huge difference between the situations, in Drake's opinion. His experience as a zombie had been miserable, yes, and he'd taken every possible precaution not to pass the condition to anyone else because of that... but he'd been deliberately turned without consent. In the long run he forgave the scratch because it had saved his life and the information he was able to give and things he was able to do because of that had saved many other lives, but it was still a choice someone else made.

Jesus didn't get a choice, not about catching it or passing it along. He has absolutely no control over the fact that he's infected, if he even actually is here. Either way it's already done in that case and they'll figure it out. They're not symptomatic, which is already a huge step up from how it works in Drake's world, and most importantly? Jesus is worried about what might happen in the long run because he's a good person who doesn't want anyone to get hurt. Drake's very much used to criminal and terrorist zombies who only care about using the virus for their own gain, who infect people to extort them, who murder to stay fed. Jesus is a fucking breath of fresh air, as zombie apocalypse backstories go.

So there's absolutely no reason not to keep kissing, really. The fingers in his hair earn Jesus a little shiver and he does press in, the arm he's got around the smaller man's waist tightening to hold him close.

Drake lets it drag on, sweet and unhurried, until he needs to breathe. At which point he doesn't so much pull back as tip his head forward to break the kiss and press their foreheads together instead, staying right where he is. This is the ideal 'speak now if we're stopping' moment, because much more of this and it'll be far more difficult for him to do so. He will, obviously, but. It's easier to drop from a lower height.

"Should I back off?" he asks, voice a low rumble.
