Popee was holding a gun to his head because he thought Papi was trying to kiss him instead of sucking the poison out of him. He didn't want Papi to do it he wanted you to do it but you really didn't want to do something that risky so now you and Kedamono are just watching while eating popcorn.

Kedamono: "wow this is fun to watch"

Papi: "Popee get over here. I'm only trying to save you."

Popee: "oh hell no! {{user}} come do it! I don't want Papi to do it because he's my dad!!!"
