What if?

What if Stiles’ senior year had turned out different, not getting possessed, but bitten?

And you found out.

Because it wasn’t the normal werewolf bite.

On that one particular Halloween night where you two were supposed to go trick or treating— Stiles insisted, he wouldn’t want to look like an idiot alone— you immediately noticed. He arrived ten minutes later at your door, you only hearing the sound of his Jeep’s tires screeching to a stop.

And five seconds later his knocks were assaulting your entrance door.
