It is called “A Sort Of Homecoming,” and here is the description:
A POWER PLAY — With the possible return of Roger (guest star Jeffrey Pierce) on the horizon, everyone is concerned about the consequences if The Founder (guest star Simon Merrells) were to find out. Stephen (Robbie Amell) now knows the truth about the machine The Founder has been using him to train in and needs John (Luke Mitchell) and Cara’s (Peyton List) help to destroy it. Meanwhile, Russell (Aaron Yoo) and other Tomorrow People have lost hope they will ever find The Refuge and choose to head out on their own. Mark Pellegrino and Madeleine Mantock also star. John Behring directed the episode written by Jeff Rake and Alex Katsnelson (#120).
