Well, I had the impression that they were all just a bunch of interns awaiting recommendation to go further in training - but I could have interpreted that incorrectly. I do like new kid (miniGibbs) and would enjoy seeing him again. Have not heard or read any spoilers on whether or not this was a one time shot though. I like how no one expected Gibbs to receive an intern, one of those things everyone just knows.
Brooks I think it was the lack of confidence/restored by Ducky that started the ball rolling again so that Gibbs will now follow up on Lee. Ducky is invaluable. Yes, I give Ducky props too!
