"Kid, healing factor doesn't repair everything." said Tony, finally giving in to the headache that was generating behind his eyes and rubbing the bridge of his nose from this nonsense. "Do you think Cap ever didn't get a cold? Or Banner miraculously didn't have a case of the sniffles because he inhaled pollen too fast? Point is -- superpowers don't fix everything. Unless you were like a 100 year mutant with claws popping out of your forearms I don't really give a hoot what your genetics are right now Parker. You need to get checked, and at the very least, for my safe and sound mind before I walk right back through that Ultra Hole so help me god, please. Do this for me."

There's the guilt trip. But hey, Tony's being honest.
