Falling Skies is upping the ante in its story of alien invasion survivors, and in the latest installment of 2nd Watch, Wil Wheaton discusses the show’s new developments with the talent behind the TNT series.

SPOILER ALERT: Don’t read on if you do not want to find out what happened in tonight’s episode of Falling Skies, “At All Costs.”

This newest episode introduced viewers to the real President of the United States, played by 7th Heaven‘s Stephen Collins, and shed a little more light on Cochise’s (supposed) motivations for helping the humans in their fight against the Espheni. Evil Hal also showed his ever more creepy face, and Anne ran away from Charleston with baby Lexi, convinced that something is really wrong with her child.

2nd Watch host Wil Wheaton leads a discussion about all that and more with Moon Bloodgood (Anne), Drew Roy (Hal), Doug Jones (Cochise), and executive producer Greg Beeman, who also directed “At All Costs.” Check out the newest episode of the post-Falling Skies talk show below:

TNT’s Falling Skies airs on Sundays at 10 p.m. ET/PT.
