“Derek’s gone Stiles.” Stiles hates the pity in his best friend ‘s voice.
“No! No Scott he wouldn’t leave!” Stiles shouts through tears as he rips Derek’s stupid books off Derek’s stupid bookshelf in Derek’s stupid loft that he will one day come back for. “He promised,” he whispers.
Scott puts a hand on Stiles shoulder gently, Stiles looks up at him through teary eyes. “He promised he’d never leave me…”
I am also choosing to believe in the head canon I’ve just created that when Braeden calls Derek to fill him in on the new supernatural shenanigans in Beacon Hills she will off hand mention all the issues the Jeep has with it. And Derek being Derek, knowing how much that stupid thing means to Stiles, will call into the local Becaon Hills auto shop where the Jeep is at & demand they fix everything, give it top of the line stuff, and hand over his credit card to pay for it all.
