The Tomorrow People | 9pm on The CW

Season finale: Russell (Aaron Yoo) realizes his alliance with The Founder (guest star Simon Merrells) was a mistake, and tries to make up for his decision by saving Cara (Peyton List) from an Ultra ambush. Stephen (Robbie Amell) understands that he must be the one to stop The Machine and the extermination of humanity, but he fears he may be too late. Russell offers up a plan to help Stephen, but he is going to need everyone’s help, including John (Luke Mitchell) and Astrid (Madeleine Mantock), if they are going to have any chance to survive. Meanwhile, Jedikiah (Mark Pellegrino) offers John an interesting opportunity that could have them working together again.
