I used Caraway once, and Masters several times. (I always have his first name being Zachariah, because I'm sick to death of Zachary and I used to know a Zachariah so it's funny.)

And I think you'll find that khukuri was the one who came up with Charon, for her FF7/8 crossover fic Bandages. Read it. It has slash and angst.

Oh, and the proud people at the FF7 Second Story project (http://www.insertcredit.net/ff7) like to call him Zachary Green.

Whoo. How's that for off-the-top-of-me-'ead?
