- Abraham pushes his group forward on the journey to Washington, while Eugene tries to see a way out.
Abraham is driving Father Gabriel's bus along their marked path to Washington, D.C. Everyone is having a good time, loosening up and it's all smiles around. Abraham drives past a herd of walkers on the side of the road, but everything is fine. That is, until the engines give out and Abraham loses control of the bus, the vehicle popping a wheelie and crashing on its' side. The noise attracts the herd of walkers they had just passed, who quickly surround the crashed bus.
After everyone confirms their survival, they realize that the bus will soon be ablaze. The group makes its way out of the bus and begins to battle the surrounding walkers. Tara gives Eugene a knife so he can help out, and Eugene is just barely able to muster up the courage to hold a walker in place so Tara can kill it. The walkers defeated, everyone pauses to take a breath, and the bus sets on fire, destroying their first aid kit and supplies they left inside. Disappointed but otherwise unfazed, Abraham orders the group to move on, losing his temper when Eugene suggests returning to the church. After a brief cool down with Glenn, the group pushes on.
In a flashback, Abraham finally finishes killing the last of several unknown men, calling out for his wife, Ellen.
The group sets up camp for the night in a store that was boarded up and thankfully not looted. While changing guard, Abraham thanks Glenn for sticking to his promise to follow Abraham all the way to Washington. While Abraham and Rosita have sex, Eugene reveals to Tara that he sabotaged the bus before they left the church, but had intended for the bus to never be able to start, not for them to crash on the road. Appalled, Tara sternly warns Eugene to never pull such an act of sabotage again, seeing as it almost got them all killed.
In the morning, Rosita and Maggie try to convince Abraham to stay in town for the day to scavenge supplies, but Abraham refuses, revealing he's found a fire truck with plenty of water in its' tanks. The truck has a less than auspicious start when it comes to starting up the engines, but the work from attaining the truck unleashes a pack of walkers that were trapped inside the fire station. The group moves to attack, but Eugene comes to the rescue by climbing atop the engine and opening fire on the walkers with the engine's water hose. Delighted, Abraham gets to work on fixing the engines so they can roll out.
In another flashback, Abraham finds his wife and children, who are shaking in fear after his killing spree. Much to his despair, Abraham finds that they won't even let him come near him.
The fire engine doesn't get far before it breaks down again. While repairs get under way, a horrible stench blows through. The group walks up a hill to find a vast stretch of land completely overrun with a massive herd of walkers, including the one road through. The group tries to convince Abraham to turn back to find another way around the death trap, but Abraham stubbornly refuses to turn around, ordering them to push forward through the walker herds. Eugene's objection gets him a throttling from Abraham, and the group erupts into chaos as they try to calm down Abraham. Amongst the chaos, Eugene shouts, "I'm not a scientist!"
In a flashback, Abraham wakes up one morning to find his family gone, having left a note instructing him to not try to find them.
Eugene reveals that he isn't a scientist, has no way to end the apocalypse, and that he's been lying all this time simply to get protection from the walkers. He does admit that he believes Washington is still their best bet at security, believing that he was doing any traveling companions a favor by traveling with them there. The group is in shock and despair, hurt that people died trying to get him to Washington for nothing. Eugene tearfully admits his guilt at that, but says the wrong thing to a fuming Abraham when he once again asserts his superior intelligence. Abraham lays into Eugene, rendering him non-responsive before he's pulled away by the others.
In a final flashback, Abraham finds his family mutilated and half-eaten by walkers. He's roused from his despair when Eugene comes running, begging for help against some walkers chasing him. Abraham dispatches the walkers and turns away, but Eugene informs him he's on a critical mission, getting his attention.
In the present, the others panic over Eugene's non-responsive body, while Abraham collapses to the ground a small distance away, weeping.
