Okay, so, Danny was tied up for several hours, very obviously not being untied for any bathroom breaks. He either had already asked Luke and was denied or he kept quiet about his needs the whole time, not wanting to further his reputation as the kid of the group.

Could take place with just Luke in the warehouse, later on after the kidnapping and all the fighting when everyone's just starting to walk home, could even take place in a slight au where Matt leaves with everyone else.

please, I just need to see this boy pee his pants
