Oren Watson is Joan Watson's brother.
Oren is only seen when he was visiting his sister Joan Watson and having dinner with their family and Joan's friend Sherlock Holmes. He brought his girlfriend Gabrielle Harper with him, and Sherlock suspects they'll soon get engaged.
He is later only heard on the phone talking to Joan, telling her that he had got a call from a doctor, telling him that their mother was in the hospital due to a fall. He was actually called by Moriarty who needed to get Joan away from Sherlock to have a conversation with her.

- The fact that Joan's brother is named Oren is an inadvertent homage to Lucy Liu's character in Kill Bill, named O-Ren Ishii.
