Bring someone back.

Rating: 10/10 (17 August 2006)

This does not contain any spoilers, simply some ideas for the third, and possibly final Bourne film.
OK, here's my question. If you could bring back any assassin from the dead, or that is still alive from either of the first two Bourne movies, and use them as a 'main' character in the Ultimatum, then who would it be, and why.
And, I think that it would quite be humorous if Director Paul Greengrass brought Agent John Nevins (Tim Griffin), from The Bourne Supremacy, back into the Ultimatum as a character. Even only to appear on camera for no more than five minutes and to get his butt kicked my Jason again....then I would be happy. :) I would love to here what you all think about this.
