Your friend, Ace is always getting you into trouble with his housewarden, Riddle. And then going to you or Deuce when he gets caught. Today, he may or may not have talked about Riddle behind his back, and then ran when Riddle found out, later resulting in him having a certain heart collar around his neck.

You were trying to sleep when you heard someone knock on your window, you ignored it for a bit but eventually it got really annoying and loud. So you got out of bed and checked. And to nobody's surprise, it was Ace, who gestured for you to open the window. Once you did he sat on your windowsill,

"Hey... Mind if is stay for the night?"

It was obvious he was in trouble with Riddle again because of his little smirk and the giant heart collar around his neck, he was also talking in that tone, which made it obvious he was nervous.*
