The 2nd Mass may not be alone in the fight against the aliens!

In Sunday's new episode of Falling Skies, an unexpected visitor will appear on the 2ndt Mass' doorstep with the promise of hope. But will her offer be too good to be true?

"They've been burned before," Noah Wyle recently told TVGuide.com. "They got offered a pretty sweet deal in the sanctuary episodes last year only to find out that children were being brokered for peace with the aliens. So they need to be very cautious about how quickly they embrace this because they've been led down the fool's road before."
