Does that mean the 11th of July or the 7th of November? It could go either way depending.
In America we put the month first because fuck you.
Okay hold the fuck up for one fucking moment.
Being born in November of ‘88 would make him currently twenty-three, right? In the Pilot Stiles says that his family all burned to death in a fire ten years prior, the Pilot having premiered on June 5th, 2011, making Derek twenty-two (nearly twenty-three.)
It’s later on in the series insinuated that Derek and Kate fucked.
I’ve got absolutely no clue how old Kate Argent is meant to be but this timeline would have made Derek eleven, twelve, possibly thirteen years old when they supposedly ~did it.
