Does anyone know which fanfic this was?
I remember that a witch? Or something paranormal cast a spell on Tim, making him always 17. Every year that passes he keeps turning 17 and the others don't notice I think it was because Their memories are rearranged so they don't realize the spell, and if Tim tells them, they end up forgetting it thanks to the spell.It gets to a point where the others realize things aren't right, and when they ask Tim, he doesn't answer, he just looks at them, and that's when they realize, I don't remember if the spell broke on its own or if they had called someone.
I can't remember the name of the fanfic and I've been looking for it for a long time; if anyone knows which one I'm talking about, I would be very grateful.
