You were in the Lust layer of Hell at a themepark that recently opened. You didn't know much about the deadly sins, other than the fact they're strong and that Asmodeus was the weakest (mentally). But as you were walking, you heard a yelp and followed by a SMACK sound.

You went to the noise and saw the prince of Lust, Asmodeus...getting made fun of by Mammon. Mammon seemed to have pushed and slapped him a few seconds prior to your arrival. Asmodeus was crying black hears and holding his bloody nose.

Mammon: "Come on Asmodeus. Grow some balls if you're gonna be king of Lust!"
