"Young Bloods" is the 14th episode of Falling Skies and the fourth episode of the second season. It was written by Heather V. Regnier and directed by Miguel Sapochnik. It premiered on TNT on 1 July 2012 and drew 3.39 million US viewers. While on patrol together, Ben and Hal try to help a young boy and wind up having their bikes stolen. The hunt to recover them leads them to the discovery of something much bigger. Matt is put in danger, and Weaver is reunited with a family member.
Matt gets used as skitter bait by two members of the Berserkers. When Tom finds out he chews both of them out for putting his son at risk. Matt feels like his dad has embarrassed him in front of the people he was getting respect from for being courageous. While on patrol together, Ben and Hal wind up having their bikes stolen. The hunt to recover them leads them to the discovery of a group of "Lost Boys" including Weaver's daughter (and Diego's girlfriend), Jeanne. Ben and Hal offer the young group and their leader Diego supplies and support from the 2nd Mass. Diego, Jeanne and two other boys leave with Ben and Hal. They gather supplies from the 2nd Mass while Weaver and Jeanne reunite. Lourdes finds out from Diego that Northern Mexico (where her family lives) was totally destroyed. Jeanne returns with Diego and the other boys with the supplies after promising Weaver to return shortly. Upon arriving at the youth's hideout, they find the place trashed and only one boy left who managed to hide from the aliens. They return to the 2nd Mass where Diego and Weaver have problems developing a plan together to free the youths from the Harnessing facility they suspect the captives have been taken to. Diego, Jeanne, and the other youths leave on their bikes after storming out of the meeting, intending to act quickly to free their comrades. Tom finds out that Diego and the other youths took Matt with them and the 2nd Mass sends out a rescue crew without a clear plan. They break into the facility and storm the Harnessing room saving Jeanne and Matt just in time. Hal sees Ben interact with one of the Harnessing creatures where his spikes glow. The group destroys the facility as best they can and return to camp. Jeanne leaves with Diego after leaving a note for Weaver letting him know she wants to wait out the invasion in hiding with Diego and the other youth.
