Marc -dripping his poison again
 

In the diary room with Joel, turning the conversation around to Harry again and again. Even when Joel wouldn't be drawn into it and suggested that it wasn't good for the house. Marc said to Joel if you were doing something wrong I would tell you and you would stop but not Harry?!
Face it Marc you have now met someone that won't do as they are told!

Him being annoyed by Harry - it's like a kid having a tantrum just to get something from his parents but they just ignore it.
I'm not a Harry fan but at least she has the guts to stand up to him. Kudos for her on that.

His face was a picture when Simon suggested that he and Harry talk and try to sort things out. That was definitely not how Marc expected the other HM to view the situation, he thought he could turn them against her by saying how scary she is and a bomb waiting to off!
