I was worried that he'd have run out of power (or at least relative power) after the Ogre extinction event and would have to let the guy go (until he could rest up and hunt the guy down again). Or, well, I was more worried about the storm that would have turned up in the chat about "letting people go" even when there was a valid enough reason for it.
But luckily he saved a bit of power (and relative strength) by dodging out of the final Ogre killing (while the guy was still wanting to be friends/allies) and then did the fireblast polka. (With a little help from his friends).
And indeed, it was a metal death scene (although the guys creepy near-immortality helped a lot with the metallicity).
