"It is rumored that the redhead that picks up Gibbs in some episodes is actually Sean Murray's mother (who is married to Bellasarius, the creator/director) making Murray his stepson. There was one episode where they were at the elevator, leaving NCIS and she spoke softly as they got into the elevator which I thought would give her "speaking credits" and be listed in the cast, but alas, it wasn't meant to be. Does anyone know, with 100% certainty, who she is?"
