Not saving them is also an option [And a few other things are an option]

The one where the dog begs for it

Fandom: Teen Wolf

It was already too late when Stiles arrived in the room. The Alpha pack had Derek by the throat and Scott was cold on the floor. They wanted him, not them. And now, because he's been too slow, his boyfriend, his true love and his brother were dead/about to die.

"You wanted me, right?! You'll never get me alive! Not after this!" He screamed as he shoved the knife he's been holding into his stomach.
Derek, wide-eyed, watched the boy he wanted to propose to kill himself. The smart, witty, sarcastic and usually happy boy he loved, just killed himself. He broke. He started begging for death. He wanted to be with his love. And he got it. His head fell on the floor as well as did his body both with a silent bump.
