The Beginning of the End

The Beginning of the End is the thirtieth episode of the third season of Ben 10: Ultimate Alien, and the fiftieth episode overall.
==Synopsis==
As the final battle between the Forever Knights and Dagon's Esoterica heats up, Ben finds himself caught in the middle of an intergalactic showdown.
==Plot==
As Ben and Gwen are with Kevin in his garage as he finishes making his car submersible, they are attacked by the Esoterica, who are destroying anyone who stands in the way of Dagon's return. They fight off the Esoterica with Ben as Four Arms and Gwen is able to capture one of the members with her mana, as they can't teleport through mana. Kevin interrogates him and they are able to find out that the Flame Keepers' Circle is planning to let Dagon into this dimension.
The team go to the Flame Keepers' Circle headquarters and find out that none of the members are there. Ben transforms into Clockwork and uses his powers to show that they have all left to free Dagon. Meanwhile, Sir George is at the Area 51 fortress, rallying the Forever Knights to fight Dagon. When Ben, Gwen, and Kevin arrive at the location of the seal with the Rustbucket 3, they find the Forever Knights and the Flame Keepers' Circle at war, and neither side is winning. Ben asks them to land the Rustbucket 3.
Ben tries to tell the Knights that he is here to help but the Knights refuse to listen and attack them. They force Ben and the team back into the Rustbucket 3, and Ben transforms into Goop to fight them. After a difficult fight, they are able to defeat them, and Gwen creates a mana shield at the door of the Rustbucket 3, which was not closed, to prevent the other attacking Knights from coming in.
Gwen then senses Esoterica soldiers in the Rustbucket 3, but still in between dimensions, watching the team without attacking. Ben convinces Gwen that they must leave the Rustbucket, and Gwen uses her shield to push the Forever Knights out of the way, as she, Ben, and Kevin exit. Gwen uses her powers to point out where the Esoterica are entering this dimension, and Ben transforms into Fasttrack to knock them out before they can attack. Once that is finished, they proceed to the seal, but realize that they cannot move through the many battles occurring to get there. Kevin has an idea and tells Gwen and Ben to follow him. They fight their way through, reaching several high-tech catapults that the Forever Knights are using. Kevin uses one to launch Ben to the other side of the canyon and he transforms into Heatblast in mid-air and proceeds to the seal. Gwen then remarks in regret that she could have simply teleported him there.
Sir George, Winston, and other Forever Knights are approaching the seal. As they get close, Winston informs Sir George that he will protect him. While passing through the caves in which the seal is set, they are attacked by Conduit Edwards, who fires an energy bolt at George while he isn't looking. Winston jumps in front of George and takes the blast for him. George turns around and attacks Edwards, who moves between dimensions for a while, firing at George. George is able to stab Ascalon through Edwards, killing him. George runs over to Winston, who tells him that it was an honor to be his squire, then dies. George says that Winston died not a squire, but a knight, and that his death will not be in vain. He runs forth to the seal.
George reaches the seal and hears Dagon's voice. Dagon claims that he will rule this dimension and take over it. The seal cracks and Dagon lets out a minion of his, to destroy George. This turns out to be Vilgax, who has being reborn with Dagon's power. The other Forever Knights attack Vilgax, but he easily defeats them. At this moment, Heatblast bursts through the ceiling of the cave and lands inside.
Vilgax then moves forward towards the seal and breaks it, though it remains intact and in place. The cave wall around it crumbles and reveals Dagon's dimension behind it.
