"Oh. Oof..." Donnie looks a little sheepish for his direct question at that. "The most that ever hits my fam now and then is the flu and it's the worst."

How does all that resolve itself though? No wait, stupid question, although that does make him wonder how the properties of a spider factor into all that. "You probably lucked out that you didn't end up sprouting extra legs and stuff along with the spider strength. Don't think the mutation deal was exactly painless- maybe we just don't remember how it went since we were...well, baby turtles at the time, but I gotta say, there's a lot of readjustments in bone and body structure and that was just watching some guy turn into a fish."

Chemistry! Despite it being homework, Donnie looks somewhat excited as he has a look, although he does pause, distracted by the mask hanging off the back of Peter's chair. Oh right, now he remembers where he's seen this design before. "This looks like the gear Tony has in the forge-" he says as he picks it up.
