Ostensibly, ignition is a Mcgee episode, but it turns out to be much more.
Colonel bell, who was last seen being carted off to a mexican prison is out, and being represented by M. Allison Hart, a lawyer who has set her sights on taking down Gibbs.
She just happens to work for law firm Wolfram, hart, and donowitz.
You may remember Wolfram & hart from angel, the multidimensional evil law firm.
While I would love to see how Gibbs and team would take on vampires, werewolves, and other assorted monsters, it would be the death of the show.
