Tomorrow People Getting Interesting!

There was a big reveal in last evenings episode of Tomorrow People. At the end of the episode we discovered that Stephens mother was one of them. I always suspected the mother had powers or knew more than she was letting on. It does leave a lot of unanswered juicy questions for upcoming episodes. If Stephen's mother had powers all along, how come didn't she realize he was breaking out instead of  having whatever psychological problems she kept stating he had at the beginning of this series? I'm sort of angry to learn she has these powers but led Stephen believe there was something wrong with him. I'm guessing we will find out her motivation behind keeping this a secret from Stephen. I'm also wondering how she has managed to keep her powers hidden from Ultra. It's also unclear if she know the real reason Stephens father left. Then there was the whole situation underground with a Kara/John power struggle. Kara felt betrayed by John when he went against her orders not to take Cassandra back to Ultra. As a result of this, they had a confrontation ending with her kicking him out of the Tomorrow People. Clearly Kara is feeling threatened as it was a cold move. I'm guessing she is going to soon run into trouble and need his help again at some point in the future. This show just keeps getting better and better.
