Sollux is just plain spacing out during Kanaya and Eridan's arguing/pleading, whatever it is... and as embarrassing as it is to admit, he only managed to zone in because the number two was mentioned. He sits up straight, looking back to Eridan in slight surprise. He knew Eridan was afraid of Kanaya, knew (sort of, it's a bit fuzzy) from the castle that Eridan had been killed by Kanaya, but he never had stopped to think much about how one would die via chainsaw.

"Wait, she cut you in two?" And, once again the very most non-helping manner, finds himself smirking and laughing a little. "Holy shit, I wish I had seen that!"
