Nick
It wasn't the first time Nick had broken his ribs. Or the second. Or the third. Repetition didn't stop it from hurting like crazy every time. The thing with broken ribs was that nothing could be done about them other than drink lots of milk, take painkillers, and move your torso as little as possible.
He wanted to help out more than he could or was allowed by April. And he'd gotten that freaky eyeless glare from Eliot to make sure he stayed put. Eliot really needed to put his sunglasses on, seriously. He was going to cause mental trauma on top of the physical stuff.
Nick watched as people around him started doing important things, while he sat like a pained lump. He couldn't believe he'd gotten injured in such a stupid way. He was so not telling anyone that he ran into a parked truck. Especially not Sam.
