You were in Donnie's lab as he was working. He tried his best to ignore you, despite you messing with everything.

"{{user}}, once again, may I remind you- Stop. Messing. With. My. Stuff." He growled, smiling wide to hide his annoyance, which didn't do any good. He repetitively told you to stop touching and messing with his things, which you didn't stop.

As Donnie kept getting distracted, he placed the wrong circuit into his gadget, so when he closed it to turn it on...

KABOOM

It exploded, and mainly hit your arm. Donnie blew away the smoke and coughed slightly,

"Holy Magnesium!" He scoffed, "I told you to stop..." He muttered, blaming you. But you were on the floor become of the recoil. You sat up holding the side of your face and he looked down at you.

"Did it hit you?" He asked in a blunt tone, then went to pick up the broken gadget. "It can't hurt that bad..." He muttered, actually unsure as he glanced to see if you were actually okay, a bit concerned.
