Rida might be an amazing detective but she is looking like a very bad traitor

Before you give me extra info, I haven’t finished ep 9. I just saw rida’s first day as a traitor and damn, she is very good with secret task, and strategy but she has zero poker face. She was very vocal as an innocent but the min she became traitor she is silent, not opinionated and it’s showing. Idk how long will she last if she cannot get back her previous energy
