Sometimes Derek looks at Stiles when Stiles thinks no one’s watching him. He looks at him and he doesn’t see the sarcastic jittery kid who’s always so full of energy and the urge to jump at the opportunity to do something, to draw out a plan of action or a rescue mission. Instead of that, he sees a man who’s been bruised and battered and left much worse for wear. He looks at this kid, but he sees a man who is tired, who has seen and done things men twice his age only experience in their darkest nightmares.
Sometimes Derek looks at Stiles and can’t help but wonder how far this kid is willing to push himself, how much more will he sacrifice and how long will it take before he finally doesn’t have anything left to give. How long will it take before Stiles finally breaks.
Sometimes Derek looks at Stiles and swears he’d give his life before he let that happen.
