[ gen is lucky that john has had ten thousand years to hone what little self-control he has and manages not to give in to the murderous urge seething inside him right now. more than just the desire to dissipate gen, but to shatter his Shard entirely. john is angry enough to want it, if only so that no one could ever throw that weakness in his face again. no one ever said it was a justified reaction. ]

You haven't figured it out yet? [ some of his anger gives way to an awful grin that can mean nothing good. ] You won't die until I let you. It's quite easy to keep you lingering at the threshold indefinitely.

You're right though; I am taking it out on you. I didn't have to do any of this to get the necklace from you, but that would've been a waste of a perfect opportunity.

[ with gen staked to the ground and what's already been said, it's not like john has to hold back to protect his image here. humanity is now just a mask for someone who lost touch with his a long time ago. ]

I can heal you as easily as I can hurt you. Even growing that arm back is possible. [ not that he's going to. ] I can make all of this stop and go away, but whether that happens now or later is up to you. The only person who suffers for your stubbornness about this is you.
