In the movie he promises Ethan he'll not drink human blood again and sticks to this promise throughout the series only hunting animals, something other vampires including Sarah and Erica find disgusting, though he happily drinks bagged human blood again in "Blood Drive" and "Fanged and Furious" where he fights over a phial of it with Erica . In "The Date to end All Dates - Part 2" he shows courage (or complete stupidity) being ready to face a hooded menace until he finds out the intruder is his vice-principal, only at this point does he cow down and runs . He later displays his loyalty with Erica when he says that "if there's a fight coming I want to be here with my friends", he only avoids the battle when placed under Anastasia's powerful glamour . Rory's last name "Keaner" was shown on a computer screen in episode "Siren Song". </P>
