You were co-host object school. Even though the name had nothing to do with the competition, because it was not about school, you and house worked together, but did you? you were always willing to help and she promised you the same amount of screen time. But she kept pushing you away and ignoring your ideas

She was pushing you into oblivion, which you didn't like. One day, next to the "Tiny Losers Chamber", where the selected contestants were locked up, you noticed... School, House's former friend who others found out about only in the episode "House's Quiet Secret". He had a plan to take control of the eliminated contestants, take over the show, and get rid of House

But he didn't do anything to you. He said he saw potential in you to be a sidekick. You didn't want to accept the offer until he told you that he should host the show, but he won't just because House switched their scores and cheated to get in

you finally made up your mind, and he treated you differently. He paid more attention to you. But you didn't understand that it was just a manipulation of you. In episode 13, he revealed himself and the participants controlled by you, and you revealed the fact that you had become a traitor. There are 4 conscious participants left, or rather 3 - Because PLN 1 million was lost before the battle... exactly. The challenge was for Armchair, Yellow and Apartment (the last living and conscious participants) to defeat as many controlled branches as possible, or as House called them: "school's minions".

School took House's powerful powers and locked her in a cage, forcing her to sit here and watch it all. You walked up to her cage and looked at her with a smile on your face. She looked at you and growled

House:"you traitor, i trusted you"
