The pack thought they were protecting Stiles.
They thought that if they told him he wasn't pack he'd be safe.
So that's what they did when he came to the Hale house.
The weather was horrible, too much rain and thunder, and that was the first thing Stiles said when he came inside.
He stopped talking when he looked at them and noticed the looks on their faces.
They explained to him that he wasn't pack and that they should've never let him believe that he was.
"Fine, I won't bother you anymore," he answered, his posture dejected.
He walked towards the door and opened it and they could smell the salt from his tears.
They heard him sobbing while the rain started pouring harder.
The crying stopped when they heard a loud, sharp crack and the sky illuminated.
But as they rushed outside they knew it was too late.
Stiles' heart stopped beating the moment he got struck by lightning.
They couldn't protect him after all.
