Perhaps the most traumatic death on this final day of the conflict was that of Captain Jack Harkness ' s grandson , Steven Carter , an event that caused his daughter Alice Carter to sever all ties with him in grief and disgust . It would be one of the final nails in the coffin for Jack ' s operations with the Torchwood Institute . Ultimately , he would abandon the institute after a six month period of travelling alone . Jack departed from Earth , and as its leader , officially disbanded Torchwood Three , leaving Gwen Cooper and Rhys Williams a safe world to raise their baby in , though because this branch was the only one known to still be operational , it meant Torchwood as a whole effectively ceased to exist .
