Gluttony was still nursing a burn to his hand and cursing very loudly as he went. He had encountered Satan's lovely little flamethrower and had gotten out of the way only just in time. Well that was just rude.
The biggest surprise was finding an enormous dragon attacking Greed and Lust, and unfortunately Gluttony wasn't able to dodge that fireball. He was used to Hellfire, he had his own, but being scorched wasn't his cup of tea. He yelled from surprise and pain as his clothes caught on fire. He fell to the floor, not because he was trying to put the flames out, but because fucking Satan had managed to murder him with his fire.
And thus ended Gluttony's current life. Until his return, of course.
