Skitters mean serious business. This is what we learned on the most recent installment of Falling Skies, "Prisoner of War."

On July 3, meanwhile, the survivors themselves will attempt to learn as much as they can about these creatures. Prepare for Steven Webber's Dr. Harris to have a very different view of the situation than Moon Bloodgood's Anne.

Elsewhere, Tom and his team will track down a few motorcycles for the 2nd Massachusetts, relying on Pope to guide them. That can't be a good idea, can it?
