Calm down? You just accused me of cheating on my wife!

— Oren to Joan, "T-Bone and the Iceman"

Oren Watson is Joan Watson's brother and the son of Mary.


Season 1[]

Oren visits Joan and has dinner with Mary and Sherlock Holmes. He brings his girlfriend Gabrielle Harper with him and Holmes suspects they'll soon get engaged.[1] He is heard on the phone talking to Joan, telling her that he got a call from a doctor and Mary was in the hospital due to a fall. He was actually called by Moriarty who needed to get Joan away from Holmes to have a conversation with her.[2]

Family dinner, sort of.

Season 3[]

When Mary visits Oren and his wife Gabrielle, she comes to believe that Oren is having an affair when she thinks she sees him kissing a blonde woman. She pushes Joan to discuss the matter with her brother. On the phone, Oren vehemently denies any wrong doing, which leads Joan to question her mother's neurological health.[3]
