After the spell, when Noah began sleeping and eating meals and feeling like a real human, he'd gotten a calendar. He used to cross off days with a delight most normal people wouldn't take in something so mundane. He'd left the calendar at Krem's when they broke up, though, and ever since then he just hasn't paid much attention to what day it is. But he has to, now, to keep track of when he needs to be at Un Chat Gris in Blue's stead. He was gone for nearly two weeks, he owes it to her. No, he would have done it either way. She needs a break, and she needs time to process Gansey leaving.
So when his birthday rolls around, he knows. He doesn't feel like a party. He doesn't feel like anything, he just knows he doesn't want to be alone. Blue isn't at Hywel and he doesn't want to bother her with something trivial, so Noah respects her desire for privacy and decides to disrespect Ronan and Adam's instead. He appears where they are, in bed, and sighs up at the ceiling.
"Hi."
