Rocky learning Grace's favorite superhero is Spiderman and after a bit of research being like "am mildly radioactive and spider shaped, want bite from Rocky, question?" and Grace can't tell exactly where the joke ends and a genuine offer begins
grace sits in silence for a minute weighing his options and rocky has to go "is joke. would burn grace" and grace goes "I KNOW THAT" and rocky goes "would not give powers i dont think." and grace goes "you dont think?" and the two of them sort of sit there thinking about the extremely unlikely possibility that grace would get superpowers from that but they'll never know until they try... and then they laugh it off but grace stares at the ceiling that night still wondering how he could make it work
