"There's a Seraphim down there. Do us a favour and knock 'im back to the stone age. Preferably with a nuke."
We're never given the HQ guy's name in-game, but we always know he'll have a cuppa tea waiting for us when we come home. He's the grumpy, grizzled old fella that's taken over the kettle in the corner and will make sure you get the tea or coffee whether you want it or not.
But what is his name? Share your theories (and reasoning, if there's any) in teh comments :D
I say it's Gerald. He just feels like a Gerald.
