I disagree completely that riley is lying about seeing lucas as a brother. Now, if this episode was the very first time we heard about this then maybe Id consider it as a realistic option. However, they have been building up this brother sister angle for weeks now... And for what? Just to have it not happen? I just don't buy it. I think they are doing this so when maya and lucas eventually end up together it will make more sense when riley accepts it.
Also, this was hands down my favorite episode of the series. Zay at it once again with his comedy and charm. I loved seeing maya so exposed and concerned about lucas. I also disagree that she made the moment all about her. She made it all about LUCAS. She was terrified for him and she did the only thing she could think of to get him to not get on that bull. It was a beautiful and sad moment. All of the hints are leading to one direction. They have been for several weeks now. I don't see why they would do all of this just to not have it go anywhere. My prediction, lucas and maya will be together. Now when it happens, I'm not sure yet.
