[This is so totally karma for complaining about the weather in early winter, isn't it? It has to be. Because clearly this place wants him to freeze to death.
Stiles hates many things, but cold is definitely, absolutely one of them. Which is why in the castle, he makes his way straight to where most of the people are, his arms piled full of blankets he had in his own room, the ones that - thankfully - have chosen to transfer here. He might not have enough for a blanket fort, but damn if he won't try.
But just sitting around and doing nothing isn't his style, though. Which is why for the next few days, he can be found either assembling some notes together, chewing on the end of his pencil, or going up to everyone he knows have significant others on the island, proclaiming:]
