Ruthie
From Multiversal Omnipedia
Ruthie was a student at Pine Grove Academy and Dexter Whitlam's only friend. She often came to his aid whenever Kelly Thorndike and his friends were beating him up. When Dexter turned into a monster after taking the G-Virus and began killing the bullies who had tormented him, Ruthie begged Dexter to spare Kelly. Dexter however killed Kelly and then turned on Ruthie, and would have killed her if Mr. Venk had not appeared and subdued him using an enormous stun gun.
