The Tomorrow People is likely about to have some dire consequences when Stephen confronts Hillary about his father.

Stephen Discovers A Truth?

In a promo of the next episode uploaded on Monday, Stephen greets his father, but asks Hillary if she told anyone about him. Hillary is then seen looking shocked and afraid when it's announced how thrilled Stephen must be to have his father back.

It appears that Stephen actually is pretty thrilled since there is a moment where he's having dinner with the family as their glasses float to their hands, with the dad standing.

While things appear to be going smoothly, Stephen tells his dad that they are back at war while Cara reveals that "Founder created the ultimate weapon." This will lead into a massive fight as Stephen takes charge in the battle. But this could lead into some sort of fight between Stephen and Hillary when she tries to convince him that she's trying to protect him, which Stephen doesn't seem to believe.

"You have no idea what you've done," he vehemently tells Hillary.

Peyton List, who plays Cara on the series, recently dished to Access Hollywood on how Stephen is going to be thinking for himself while disregarding everyone else.

"Stephen has been coming into his own more and more and making decisions more for what makes sense to him and not just what would be the best for The Tomorrow People because these guys are evil and these guys are good, and I've gotta pick the side of good," she said.

The Tomorrow People airs on Mondays at 10 p.m. ET on The CW.
