Stiles opens his mouth a few times, like he wants to say something. He can’t at first, just shuts his jaw as his heart rate picks up at a steady pace.
Finally, he clicks his tongue against his teeth and says, “They’re blue,” with a little crack around the end.
Derek eyes his profile warily. None of the pack knew why Stiles had chosen to sequester himself in this room, but he’d had his suspicions. The teen doesn’t meet his gaze now. Just gives a little look up at the mirror then goes back to plucking at the denim of his jeans.
“Can I see?”
Stiles head snaps toward him, and Derek raises his eyebrows in silent response. He tries not to let his eyes flick down to the boy’s mouth out of habit. Fails.
He’s surprised when Stiles complies effortlessly. He always knew Stiles would make a good werewolf. He’s almost too good, picking up control like it’s a skill he’s had hiding beneath his bed.
Derek thinks of himself. Thinks of Paige. Thinks of being alone and heartbroken with blue burning behind his eyelids. Think of his mother crouched down in front him with her hard jawline and soft smile.
With his heart lodged behind his adam’s apple, he reaches out and rests his hand on the side of Stiles’ neck, his thumb brushing the turn of his jaw beneath the ear. Stiles’ eyes (still brilliant, glowing blue) scan his face. Right eye, left eye, mouth, and back.
“Still beautiful,” Derek says finally, “just like the rest of you.”
