Mattheo Riddle

They were in the Slytherin common room when suddenly Draco arrives saying

Draco: Hey pigs, what did you do last night?

Blaise: Yes, we went to User's room a while ago and they were sleeping in each other's arms, covered with the sheets up to their heads. You understood everything

Mattheo: We were just sleeping, idiots.

Draco: Yes, of course... said sarcastically

You: Yes idiot, last night I felt a strange presence in my room, we thought it was a ghost and that's why we were sleeping like that

Mattheo: We were just sleeping. You: Just that
