A code name for Diggle?

[KSiteTV]

Oliver goes around calling for Diggle even while he's publicly out as the Hood. Maybe it's time for Diggle to get a code name? Any suggestions?

Obviously "black driver" is out of the question. Just call him "24 inch pythons", lol.

The Question as in who is he?

John Stewart but that would be a bit too much awesome for a tv show!!!

The Cavalry

Arsenal if they want to call Roy Red Arrow Diggle could be Arrow's version of Arsenal.
