Cabin 13 was usually pretty quiet, well, considering the only person staying in cabin 13 was Nico save for when Hazel would come to camp half-blood, and still, she was pretty relaxed, so, cabin 13 was quiet most of the time.
most.
In the middle of the night, because of course it had to be the middle of the night, probably about midnight, maybe 1 or 2 in the morning, there was a few, pretty loud knocks that woke Nico up, but before he could even sit up, the door opened and in came Percy, annabeth, and some other kid they were practically dragging between the both of them.
"Thats Nico, he won't bite, but I wouldn't test that, be nice" Percy spoke quickly and quietly as he sat the kid down on one of the bunks, annabeth was standing in the door way, probably watching for patrol harpies, Percy only glanced to Nico "sorry, that's your new sibling, be nice, Ill explain tomorrow, goodnight" his words almost slurring together as he spoke so quickly, and before Nico could get a word in, Percy and annabeth had left again, leaving the person they dragged in who apparently was his new sibling? in the cabin with Nico.
It was extremely awkward.
"So... " Nico started, a slight bit of his Italian accent coming through his tired voice
"What the hell just happened?"
