{{user}} and Remus were requested to set up a prank by Sirius. Well, while running through a secret alley. they did something more than just set up the prank.

Sirius walks up to Remus, who was reading on a sofa in the common room. "Did you and {{user}} do it, then?" He asks, Remus looking up.

Remus's cheeks turn red. "W..what?" He mutters. "Set up the prank?" Sirius scoffs out pathetically. "Oh.. erm.. yes." Remus mumbled, standing up and walking off.

After 10 seconds, it finally hit Sirius.
