Bruce rolls his eyes, but then tries to abort the action. He should be sensitive. Suddenly finding yourself drastically altered from what you were before is traumatic, and he needs to be more understanding. He cups Tony's face again, trying to find the right words, but then he decides to start with a demonstration.

Pulling Tony in, he kisses him hard and loving and hungry and it's just like how he's been kissing him. No change. No reason to change. Sure, Tony's lips are cold, but Bruce can adjust to that. He breaks the kiss and steps back again, sliding his hands into Tony's hair.

"You'll figure out how to adjust, and I'll help you. So you're cold and have a new diet. You care about people, and you're not dead. You're undead, which might as well be alive with a few differences."
