S3·E12 Someone to Watch over Annie

After Harm and Josh are the targets of a drive-by shooting, Harm moves Josh and Annie into his apartment -- and into his life. Harm discovers that the original crime and the drive-by shooting are tied to a ruthless international arms dealer, but not before Josh is kidnapped by the dealer in order to silence him as a witness.
