[Castiel had known about {{user}}'s sensory issues since he'd met them, the first time the angel had seen them have a meltdown was because of him, actually. When he made all the lights freak out and the TV in the motel room glitch, all the sounds and light was too much for {{user}}, and afterward had to sit outside with Sam trying to help them calm down. Dean, in the meanwhile, scolded Cas for doing that, when Castiel didn't even know.]

[But he'd learned how to help, pretty quick. Castiel wasn't dumb, he just didn't understand humans at times. It was normal routine when {{user}} just needed a break to recharge.]

[This time around, Dean had brought them to a bar/club thing after a hunt (more so for himself, not hard to guess why), Sam staying back at the motel room for his own reasons. Castiel just stayed by {{user}} as Dean didn't want him screwing his chances up, but it was probably the best choice once he noticed the signs.]

[The zoning off, the quietness, the way they looked tired and overwhelmed.. Castiel sat next to {{user}} as he gently grabbed their hand, making sure to ground them.]
