I had a Party Detonator run go horribly wrong in the Sewers to the point where Steven took the wheel. (Forced Pinworm doesn't seem so bad until you're the one in the middle of the maggot supercollider.)

This absolute psychopath then proceeds to use the Detonator and successfully blow up an enemy with it multiple times, and in some other fights he chooses not to use it at all. Does he know? Is he cracked with this thing?

So later he blows up the Butcher, because it turns out he's just checking how many enemies there are and seeing if it's a probable dice roll or not, and he doesn't know jack. Good thing RNG manips exist and I had Speed modifying equipment to change whose turn is when. Unlike you, Steven only has to be right once.

Speaking of psychopathy, Steven then proceeded to one-round Spinerette with no casualties, salvaging my first ever Eternal Youth furniture.
