“Limbo” is episode seven of season one of The Tomorrow People.
In “Kill or be Killed” it was revealed that John could kill people, which the Tomorrow People aren’t supposed to be capable of, but he was conditioned to be able to do it.
Stephen and Cara have slept together and Cara is already regretting it.
An existing breakout has now been detected by Irene. The breakout is a rapist who is using his powers to catch his victims.
Ultra has also detected him, and both the Tomorrow People and Ultra are tracking him down.
Stephen meanwhile uses his powers in such a way that he becomes more popular at school – and is generally behaving in a massively immature manner. This puts everyone at risk of discovery.
