I've been trying to find clues as to how Sam and Oliver are related. Haven't found any. I believe they said it a few seasons ago, but I can't remember. Can anyone tell me?
shareOliver and Sam are "brothers in blue", which is to say they are not blood related at all but consider one another family due to the close relationship they've developed on the job.
shareI could be wrong, but I thought one of them mentioned going to the police academy together, or being rookies together.
sharepeople probably think they're related because in episode 3x06 Shaws daughter Lizzie calls Sam Uncle Sammie...
