Dying his hair black, makes Tony look surprisingly dangerous. He's the ideal person for the assignment – he's a natural people person and he's got a way of making people open up to him. He really should have agreed to the subdermal implant, an implant in a shoe is just stupid. I always enjoy seeing Gibbs worried about Tony, Gibbs is a closed book so it's a rare thing to have Gibbs show concern.
Jeffrey is a complete nuisance, petty criminal who is apparently not cut out for life on the run. He's not exactly what he seems to be, he puts on this poor defenseless puppy routine and Tony actually falls for it. It's easy to assume that Lane is the killer but it's Jeffrey.
McGee did very well with the Deputy Secretary of State, he's impressive when he stands up for himself, he just needs a shove in the back. Loved Gibbs' twisted pride about that.
