He probably shouldn't, given Jet's fever, but Albert disregards caution and kisses Jet anyway. He pours every once of affection he can muster into that kiss, all his fear of losing the man at his side, all his want for them to have an actual life together when they can break free of this terrible place. Maybe even before. They have a life together already and though it may not be ideal, it's certainly better than facing these things alone. There's that guilty part of him that's glad Jet is here even if he wants Jet as far away from danger as possible. Even that is in this kiss.

It's not magic, and it may do nothing really to convince Jet that Albert has him right where he wants him, but it's all he has until he figures it out.
