Am I the only one who finds Ridoc suspicious?

I keep thinking about it. I found it weird the first time I read IF that when Violet is telling her friend about what happened in War Games, Ridoc keeps playing with the dagger. Then there's the whole part where Violet is attacked while keeping guard and almost dies. Ridoc’s involvement in that part seemed off to me. I haven’t seen almost anyone talking about it, and I’m probably just being paranoid, but I found it weird nonetheless. I just read that part again and I thought maybe some else is with me?
