Templar: Woah woah woah WOAH.

Cullen? Callaghan? Wait, maybe not. Is it a nickname for the first or last name?

Too hard.

Caligula? Never been too good at these things.

Culpepper? Sounds like a good coppy name.

Cullion, maybe? Sort of fits 'im.

Well Sully is short for Sullivan so it must be...

Cullivan? That sounds kinda dumb.

I know. I won't ruin anyone else's fun, though.

rapscallion?

He doesn't really know though. The only name that I could think of that even came remotely close was Collin maybe Calvin... Charles perhaps (colder and colder)
But Dick is short for Richard so I'd expect it could be anything.

Cullen.

I have no clue, I was hoping you'd tell us soon :P

Yeeaah, I'm with CJ, gotta go with Caligula.

I'm still confused; Have we seen this character before?

I've seen is used for Charles, Carl, Colin and Cullen...

Hey, Culligan Man!

MacCullen, maybe.

I'd agree with Ebony, only I'd say it was McCullen or maybe McCuller (like the author). I'd just assumed he was Irish even before the cop question came up.

the idea for the business card made me laugh...
wasn't there a TV show called Spencer for Hire?

It's Curtis.
It just accord to me. But you know nicknames are tricky. One of my friends is named Garrett. We all call him Gurt or Gurty.

Culliver? There's a bit of jaded Irish cop vibe, so McCullough maybe? (n)thing (Mc)Cullen.

Michael ("my-kull"->"'kull"->"cully")..?

Culvert! Um. McCulloch? Huh.

And hey, I went back in the archives to check on a whim, and Cully is totally one of the bodyguards in that scene back in chapter 1 with Xenophage. I guess that was when he met Scip's mom, too. Craziness!

It just occurred to me that Cully looks a lot like Jimmy Carter on this page.

Coincidence?

Rumplestiltskin?!

Cuchullain, perhaps? Everybody else has epic names! :)

Culloden? I like the Cuchullain idea, though.

Cthulhu?

I was pretty sold on Caligula, but Cthulhu is just plain genius. I think I'll toss my vote in that category.
