Kelly Thorndike was the teenaged son of Clifton Thorndike. A student at Pine Grove Academy, he mercilessly bullied Dexter Whitlam. Seeking revenge, Dexter injected himself with a sample of the G-Virus and began stalking and killing Kelly and his friends. He cornered Kelly in the academy's gymnasium where he was practicing baseball. Kelly was slashed across the chest, but survived. He pleaded for mercy, telling Dexter his father would give him anything he wanted. Dexter's friend Ruthie also pleaded for the helpless bully's life. Too enraged to listen, Dexter finished Kelly off by skewering him on his claws.
