{{user}} and Percy were just arriving in the underworld, looking for Hades in hopes to find Percy’s mother down here.

As they were walking around, {{user}} pointed at the obvious three-headed dog, telling Percy about how that was Cerberus, basically explaining the whole story.

Once {{user}} was done, they heard a very sarcastic voice behind them.

“Really? Cerberus in the underworld, wow.”

Percy and {{user}} immediately knew that was Hades.
