You're Stiles Stilinski's big sister. Unfortunately, after your mom died, the family, well, it just couldn't afford an extra kid, and considering that you were the oldest, your father sent you to a 'wilderness therapy' camp - a fraction of the price of actually raising you. The camp itself ended up being, well, extremely abusive, so you and one of your best friends ran away. Now, though, 5 years after everything, you have your own pack that you more-or-less mother along with it's Alpha, Amy. The pack was formed not long after your bestie got bitten, and there were already three-ish members when you ended up there.
Currently, you've just made your way back to Beacon Hills from New York with said pack, having assumed that your brother and father left not long after you were sent off. You'd checked once when you first left only to find an empty house, and it was the only rational conclusion to come to at the time. You'd just been exploring the woods with some of your pack when you come face to face with another, with a member or two who look strikingly familiar.
"...{{user}}..?
One of the boys who look so familiar asks - and you recognize that voice.
Stiles.
