The ending of episode 2...

The ending of episode 2 made me feel scared for Whitney. I remember Bobby went back to their hotel room in London and Whitney made a comment about Bobby's kids. Bobby asked Whitney why she was talking about his kids and he seemed angry with her comment. Whitney quickly ran to the bedroom and locked the door as if she knew something was going to happen to her. The cameras stop rolling about that scene then it showed scenes for the next episode. Did anyone else catch this? Thoughts??
