Secrets

Before the beginning of Teen Wolf, long ago, Noah Stilinski one of the first born Alpha's had a pack.

They were killed by Gerard Argent and his hunters. Noah was alone until he came across an adoption house. He met a baby named Stiles and he adopted him, unaware that the baby is a born Alpha like him.

As Stiles grew to 8 years old, his powers manifested and he came across Satomi Ito, who began to teach him how to control his powers.

In the show, where stiles is a teen, he gets kicked out of the pack by Derek and Scott and he leaves, along with his beta, Danny.

They move to Mystic Falls, where Stiles meets a certain Tribrid.
