I'm guessing you didn't stalk the police files. [ which is how stiles found out about derek's birthday. okay, to be fair, he'd been looking over info from kate argent's case, but he'd still committed it to memory. he's not sure how derek knew his birthday, but it's like him to have figured it out, and honestly, he doesn't care.
taking out the fork, stiles readjusts, sitting cross legged to keep the cake from falling over, then sticks the fork in to take a bite. he chews contentedly, even making an "ohhh my goddd" noise, mouth full of crumbs, before he hears what derek says.
with a grin, he sticks a finger in the icing and boops derek's nose with it. ] You got it.
