What if they threw a war and nobody came? Well, everybody came to the war on Falling Skies — or did they? This week, Tom stumbles on a family seemingly untouched by the alien invasion.

In Cornelius, North Carolina, Tom gets a taste of the life he could have lived: a life without Skitters or Overlords. The paranoia he shows to the kindly older man who fixes his leg, and his — discomfort? fear? — at the laughter of children, shows how far gone he is from the academic he was four seasons ago.

But everything may not be as it seems. Is there really “no fight here… no war,” as the man says, or is something more sinister going on? Even scarier: If there really is no war in Cornelius, then what does that mean for the man Tom has become when the invasion eventually does end?

Falling Skies airs Sundays at 10 p.m. on TNT.
