I'm going to warn you, that if you haven't seen this episode, you will see spoilers. I just wanted to make this for the people who are usually like me (but not this time), who don't get to see the episodes until they come out on Netflix or Vudu, or whatever you have. (I'm going to add pictures, but not drawn ones, because you nice people deserve to see the real deal.)
So lets start off with a quick reminder of what happened at the last part of season 4. Glenn, Maggie, Abraham, Tara, Rosita, Sasha, Bob, and Eugene made their way to Terminus, when they were greeted by a nice lady (named Mary) cooking up some meat. The place looks safe right? Wrong. We will get back to you Glenn.
Rick, Carl, and Michonne were also going to Terminus, when they stopped to take a rest for the night at an old, beat up car. While Carl was sleeping, the group of guys Daryl was with came out of the woods and put a gun to Rick and Michonne's heads (Daryl wasn't seen yet). Joe (the leader) was telling the rest of the guys in the group about how Rick killed one of their men, and they wanted to settle it by killing Rick and Michonne. Carl was in the car, and one of the more creepy of the guys pulled Carl out and held him hostage.
Then Daryl came out of the woods, Rick was happy to see him, Daryl got beat up by the rest of the group he was with for telling Joe that Rick and Michonne were good people. Joe said that was a lie and that went against the group rules, so he had to face the consequences.
Rick then got the gun away from his head and Joe grabbed him to strangle him, and Rick proceeded to bite Joe's neck, and rip some flesh out. Walker style. Michonne took the gun from her distracted pursuer, and shot him in the head. Daryl killed the two men who were beating him up and Rick stabbed the man who was holding Carl.
Rick, Daryl, Carl, and Michonne went to Terminus the next morning after Rick buried a bag of guns including his special revolver, and instead took a different pistol. The four snuck in, and were greeted nicely by someone named Gareth. When they are taken by another man to the main area of Terminus they meet Mary (still serving up meat) and Rick notices Glenn's pocket watch and riot gear, Daryl's poncho, and one of their backpacks all in possession of a Terminus resident. Rick starts a fight, and the four are all directed by gun fire to train car A, where they are forced inside, and they see Glenn, and his group all inside too. Rick ended with the fierce line of "They're screwing with the wrong people." Or on the special edition version of the episode, "They're f*****g with the wrong people."
Ok now onto season 5!
They started the season with a backstory of Gareth and Mary and some other people at Terminus. These back stories were woven throughout the episode, basically just consisting of how Terminus used to be before Gareth took it over.
When we got back to our group in the train, they are using belts, pieces of wood from the train car, clothing items and other things they could find to make weapons, since theirs were taken away when they were captured. Then you hear people coming for their train car. Everyone gets into battle position facing the door. The top of the train car opens and a smoke bomb is dropped in. Abraham yells, "Move!", but some aren't fast enough. The next thing we see is from Rick's perspective. He is going in and out of consciousness and is being dragged. In between his blacking out moments you can see a body being cut up on a table. Then they cut to normal perspective and we see Bob, Rick, Daryl, Glenn, and four other men, kneeling on the ground with cloth in their mouths in front of a large tub.
We don't recognize three of the men, but one of them is a blond guy who we do know.
He was in season 4 when Rick and Carol went on a mission to bring back some medicine for the patients at the prison. The guy was with a girl and he acted like they were in love, but later when Rick says they can come back with them Carol insists that they help find medicine. Rick gives the guy his watch so he can come back in two hours. Rick later sees the girl's cut off leg, and her body being eaten by walkers, but the guy wasn't seen again until now.
Two Terminus workers then hit the blond guy and slit his throat, threw him over the tub, and moved on down the row to the next three guys, who we didn't know. Just as Glenn was about to get hit, Gareth comes in to ask the workers what their shot count was, which saved Glenn's life. Gareth then tells Rick that he saw him bury a bag, and asked what was in it. Gareth threatened to kill Bob if Rick didn't tell, then Bob was saved by a huge explosion. We will hear more about that in a minute. Gareth runs out of the room and one of the workers tries to get the other worker to come with him to see what happened, but while they are arguing Rick pulls a wooden stake from under his pants leg, where he could luckily grab it with his hands tied. Rick cuts himself loose, and stabs the two workers. He then cut Daryl, Glenn, and Bob loose, and they equipped themselves with various knives that were previously used for cutting up humans. Then we see hanging, limbless torsos with most of the meat cut off.
We are then shown Carol and Tyreese and Judith walking along the tracks to Terminus when a walker comes out of the woods and starts to follow them. Tyreese tells Carol that he can't kill it. They are then run off the tracks by a herd of walkers who are coming right for them. You then hear gunshots from Terminus, where they are clearing out walkers from the fences. Tyreese and Carol go through some more forest until they find another Terminus worker chatting with someone on a walkie, and setting up fireworks. Carol then puts a gun to his head threatening him to drop it. They tie him up and Carol gets a hint from him that her people are at Terminus, so she leaves Tyreese with Judith and the man, and goes and camouflages herself in walker blood and mud. She takes a firework and a gun, and goes up on a hill above Terminus.

She shoots a large gas tank with the firework, which causes the huge explosion. Carol sneaks into Terminus and makes her way to a room full of stuff that had been collected from people who came looking for sanctuary. In there she finds the watch that Rick gave to the blond guy, and she turns around to see Daryl's crossbow on the table. She takes the crossbow, and heads out the door and goes into a room where she meets Mary who she shoots in the leg, because Mary won't tell her where her people are. Carol lets some walkers into the room, and that's the end of Mary.
In the train car the rest of the group is preparing for battle and Eugene is asked how he is supposed to save the world. He explains and says it's like fighting fire with fire.
In between all this, Tyreese is with Judith and the Terminus worker in a cabin. Tyreese puts Judith in a makeshift crib, and looks out the window at the walkers. When he turns around the worker has his hands around Judith's head and tells Tyreese to drop his weapons and go outside with the walkers, or the baby dies. Tyreese obeys, and we hear him yelling. Later on he comes back in, and the worker backs up. Tyreese then beats the worker to death.
Somewhere else in Terminus Rick, Glenn, Daryl, and Bob are dodging walkers, and let a man out of a train car who yells, "I'm free!" and then gets bitten by a walker. They then make it around to train car A and let the rest of the group out. They then hop the fence narrowly escaping the walkers. Rick turns around and shoots at Gareth with a gun that he found and we see Gareth get hit, but we aren't sure if he is dead. Everyone escapes, and they head to where Rick buried his bag of guns. Everyone is standing around when Carol comes walking up behind them. Daryl sees her and runs right at her and gives her a huge hug and she hugs back, and he starts to cry a bit.
I cried at this part and for the rest of the episode.
Anyway, so then Carol leads Rick to where Tyreese is, and Rick sees his baby and runs and grabs her from Tyreese. Rick and Carl hold Judith and cry tears of joy. The whole group is together now, and they begin to walk down the tracks to wherever they are off to next, with Carol and Daryl walking side by side, and Carl holding Judith. Rick sees a Terminus sign, and crosses it out with something he found in the dirt.
So that was the recap of episode 501. And they had a scene from the next episode which showed someone in a mask walking up to the Terminus sign that Rick crossed out and looking at it. He took his mask off, and it was Morgan! Morgan is coming back! I'm very excited!
So this episode was probably my favorite episode, and I can't wait to see what happens next!
*Extra Note* I'm going to try to add a post once every week, but I haven't decided if I should have an exact day that I upload on. I'll think about it. Thanks for reading!
