Question about Danielle

Why did Danielle say BRob is a traitor for what he did if one that's the literal name of their team, shocking a traitor acted like a traitor, and two she herself voted for Bob too. She could have just followed one of the other votes that people said like Ciara. But instead she still picked Bob which could in a way be interpreteded as also betraying him which to me feels like she was being a bit of a hypocrite. Does anyone know or have any guesses for why she said and thinks all this?
