On the road to Charleston at night, Tom thinks about saying good-bye to Ben.
He wished him luck and hugged him. Ben assured his dad it'd be OK and they'd see each other again. Then he walked away.
Back on the bus, Tom doesn't want to stop even though Anthony says they're low on fuel. Matt gives his dad his will, because everyone's saying they're not going to make it to Charleston.
In another truck, Tector drives for Weaver.
Hal drives with Maggie, with Pope in the back. "All this Beer Duty is starting to take its toll on me," he announces. But they can't stop til they run out of fuel.
Maggie says she is ready to kill Pope and Hal assures her he's thought about it. She doesn't think he has that darkness in him.
In the medical truck, Lourdes is having a hard time focusing on the patient.
Tom has a blister, but doesn't bother Anne with it.
Weaver notices Tector avoids the word "sir," but he can tell from his skill with a weapon that he has a military background. They're about to talk about it when the truck hits something. It's a harnessed young girl.
Anne looks her over. Her harness isn't glowing, so Anne thinks it's damaged. Weaver wants to leave her in case she's a spy.
She wakes up and asks about her brother Tyler. Weaver decides to lock her up in the back.
Hal hopes Ben is waiting for them in Charleston. Maggie tells him to trust in fate, noting how much her life has changed for the better. Their truck starts to overheat. Pope tells them to keep going, he knows there's a river up ahead -- he used to take the road to visit his kids in Florida.
On the med bus, Tom wonders what will happen to the kids who have been harnessed. Matt goes to get a look at the girl, who has scales starting to grow on her face. He brings her food and mentions his brother was harnessed. He offers his hand and she extends her, which is already half alien, webbed with long fingers and nails.
Hal pulls the scout truck over and worries what will happen to the others without them in front looking out. Pope says the radiator hose has a hole and sends Hal for water. Maggie stays behind to watch him.
"What's going to happen when he finds out the truth about you? About who and what you really are, what then?" Pope asks Maggie.
In the med bus, Anne passes a sign saying they're 146 miles outside of Charleston. The water tank is about a third empty from a leak. Tom tries to fix it and yowls in pain.
Lourdes hovers over Jamil's tools, collecting them.
Stopped on the side of the road, Pope tells Maggie that people like them don't belong in Charleston. She thinks nothing good comes from Hal finding out about her past, but Pope urges her to tell the truth.
Ben talks to Jenny the harnessed girl. She explains Tyler and some others kids became her siblings when they were "joined to the same guardian." They were all killed by humans. She says she loves her guardian, she took care of her. Ben tells her the 2nd Mass can be her family. She asks what's in Charleston.
Weaver continues interrogating Tector and figures out he was a Marine. He admits to being a gunnery sergeant who served in Iraq and Afghanistan. Weaver wants to get Tector a leadership role, but Tector plans to leave after Charleston. He doesn't want to talk about it.
Ben tells Jenny all about Charleston, reading from his journal. He wants her to come so he'll have a friend. She thinks people won't accept her.
Jenny starts to feel something and then says that she can feel Tyler near. A skitter jumps on the side of the bus. They pull over to inspect but don't see anything.
Pope gets the truck started again. Hal tries to figure out what route the convoy would have taken. He drops hints at Maggie to fess up. Hal tries to ask Maggie about it.
She tells him when she got out of the hospital, she got overwhelmed and wanted to get away from everything. She got into drugs and stealing to support her habit. She got caught and ended up in prison. She had a baby boy in prison, but the state took him away.
Pulled over, Tom notices they've seen no sign of Hal, Maggie or Pope for 250 miles. Weaver promises they'll circle back after they reach Charleston.
Back on the truck, "Tyler" jumps on the bus again, Jenny's harness lights up and she easily breaks her chains. She tells Matt she has to go. She knocks him over and runs off the bus, harness glowing into the night.
Back on the road, Tom checks on Matt, who has a bump on his head. Tom explains Ben is only with the rebel skitters so he can fight with them to protect his family. Matt's worried Ben might not come back. He writes in his journal.
Lourdes goes to check on their severely dehydrated patient and realizes he's dead. Lourdes is not handling things well.
Maggie prods Hal for a reaction to her news. He wants time to think. Suddenly there's a bright white light in front of them. Hal slams on the breaks.
Weaver thinks Tector feels guilty over Boone's death. He tells Weaver about leading his patrol into an ambush in Afghanistan. Weaver start yelling at him that he killed those men, and Boone, then says of course it's not his fault. The enemy killed those people.
Weaver knows what it's like to lose people. He contemplated leaving after they lost all those people in Fitchburg, but he knew he couldn't desert his people.
Suddenly, the whole convoy stops.
Lourdes apologizes to Anne, saying she's just still mad. Tom and Weaver and the rest go to inspect Charleston. The main bridge into town is destroyed. The city is in ruins, bombed beyond recognition. They take it all in, realizing their dream is dead.
On the med bus, they try to cope with a day of failures. Tom was so sure Charleston was real, he knew how badly they needed it. "I don't know where Hal is and I don't think I'm ever going to see Ben again, and my nine-year-old just made out his will," Tom says.
Anne tries to convince him not to lose hope.
Weaver tries to figure out what to do next. Tector tells him his people need him, even if Weaver doesn't know what to say to them. "I respectfully suggest you make something up, sir," Tector says, saluting him.
Weaver fires a shot into the air to get everyone's attention. He tells people he should have known better, but now they have to work harder to make the dream happen. He tells everyone they're going to get back in the vehicles and forge on.
They hear a rustling in the woods. It's Col. Jim Porter from the First Continental army. He heard the shot. He presents Weaver with a bag of strawberries.
He tells Tom there's a legend building around him.
The strawberries came from the new capital of the U.S., Charleston. Porter explains that looks can be deceiving. Hal and Maggie are with him. Hal's confident they'll see Ben again; he thinks fate owes them.
