Which character did you wish had left sooner?

Of all the main, recurring, or guest characters, which ones would you have wished into the cornfield before the end of the episode they were in?

Personally, I never really cared for Director Jenny Shepard or Dr. Samantha Ryan. And I'm not a fan of DOJ Inspector Gabriel LaRoche so far - LOVE Seamus Dever, hate the NCIS writer's cookie cutter "here's the over-arching villain for this season" approach to storytelling.

There are better storylines!

I'd rather see a "bad guy" character become so beloved over the course of a season or two that his betrayal of the team is a shocker for the audience instead of the hackneyed he starts off as a bad guy who you hate and now we have to sit uncomfortably as we slog through every agonizing episode until he finally dies.
