The general assumption seems to be that the redhead is just a friend. Gibbs flirts a lot for a man who has a girlfriend/if bạn remember the blond he kissed in S2,ep.12- " Doppelgänger"/, if that is what the redhead is, but he does not seem the type to cheat hoặc be a player.
We never find out who she is as a character she isn't được trao a name. She's just the mysterious redhead in the silver chuyển đổi, chuyển đổi được who picks up Gibbs occasionally. lol. I do know in real life that it is Don Bellasarius'(sp?) wife.
No one knows-one of Gibbs misteries.:) But it seems she is thêm a friend than a potential lover,because in the time Gibbs was with her,he got out with other women.
She was never được trao a name, a face, hoặc a real plot concerning who she is. She was probably a girlfriend hoặc a lover of some sort, but she seemed to disappear after the first season. She was probably written to hiển thị off Gibb's mysterious nature, and his tình yêu of red heads. :)
This is as much a câu hỏi as an answer. I think the red-head is Mark Harmon's wife Pam Dawber w/a red wig to fit the well known preference of Leroy Jethro Gibbs.The character is probably a friend with occasional benefits.:o)
