All that was left was Scorcher and the Keeper. However, there was one problem: the sun was coming time to think, Marceline transformer into a bat and flew into Finn's backpack.
Ice King stopped fighting the Keeper and blew a huge storm of frost over the landscape. He decided it was time to end this. He interrupted Finn's fight with Scorcher, flying right into Scorcher and both of them disappearing into the horizon.
Jake took care of the last of the Cave Dwellers, while Finn and Water Princess went to help Flame Princess. However, things didn't quite go as expected. From his skeletal arm, the Keeper shot a green fireball at Flame Princess. She charged into it, but, contrary to her expectations, it was cold. As the fireball consumed her, her fiery body went lukewarm. She started to sputter, and a small green light took hold in her eyes.
She turned towards Finn. She fired up again, this time on the side of the Keeper. But as she approached Finn, she swerved towards Water Princess, leaving only Finn to deal with the Keeper. Finn, forgetting the warnings, charged his sword to full power and struck wildly, but masterfully, at the Keeper, who struck precisely.
"Give up!" yelled the Keeper as he and Finn struck at the same time. The force made them both fly backward.
"Never," Finn responded.
The Keeper put his hand over his face, and for a second Finn thought he was merely expressing disappointment. However, when he took his hand away, he revealed half of his face was now a skull.
"They tell me their secrets," he said, and without hesitation, he charged at Finn.
At this point, Water Princess could only be described in one word: pathetic. She was slow and her fighting skills, if any, were sloppy. Meanwhile, Flame Princess grew even more powerful. It was no wonder that her fiery attitude and powerful skills had attracted Finn's adventurous personality. But at this point, it was hopeless. She prepared to be boiled. She braced herself against a fireball, but as it approached, a yellow wall had blocked it, and she heard a loud "Oooh!".
It was hopeless. That's what was going through Finn's mind. The Keeper was only going to get more powerful. Finn racked his brain for ideas, when one suddenly came to him. He didn't know if it was going to work, or what would happen if it did, but it was his only chance.
"Jake," he called out. "Could you hold him off?"
"I'm kinda busy," Jake called as he continuously blocked fireballs aimed at Water Princess. Finn had no other option, until a beam of energy shot down. He instantly found himself in the ship from before.
"Hello," the man from before called out. One of the Seekers.
"Hey," Finn said. "Could you drop me off at the Candy Kingdom?"
"Certainly," the man said. He pulled a lever seemingly out of nowhere, and the bottom of where Finn was standing opened. Those jerks had sent him right back into the battle.
However, surprisingly, he found himself at the Candy Kingdom, still in ruins. As he expected, Princess Bubblegum was there.
Finn had a thought. They had said that he healed fast, and it only took a second after Finn told the man where he wanted to go that he was dropped off. Could they have been manipulating time somehow? He didn't have time to think it over.
"Finn, is it over?" Bubblegum asked.
"No," Finn said. "But listen, I have a plan, and I need your help."
So, it was that Jake had to take over for Finn. Meanwhile, Flame Princess, continued to shoot at Water Princess. Steam came off of Water Princess.
"Hahahahaha!" Flame Princess laughed all the while. Then, abruptly, she turned her head, as if in curiosity. "Would you like to hear the secrets too?"
"Stop it!" Water Princess shouted.
"Yes!" Finn celebrated his short victory. "Now, I can defs defeat the Keeper."
The ship returned again. Finn ran inside one of the slightly melted walls, and Marceline flew out of Finn's backpack, where she had still been hiding, and rested in the shade. Finn ran back outside, and he and Princess Bubblegum were transported back.
Finn reached the battlefield, only to see Jake beaten and bruised, and Water Princes being boiled. Finn reached into his pack and pulled out a peculiar object.
It looked like someone had attached the head of a megaphone to the handle of a tennis racket. It had numbers on it: 1 through 4. Finn took hold of a switch, pulled it up to four, and blew into the object. Out shot a fourth-dimensional bubble, and it began expanding. It became a miniature black hole.
The black hole began to suck the Keeper in, just as Jake stretched away.
"No! Hear the secrets! I will not disappear! I, Orlock, will now burn inside!"
It was too late for escape. It sucked in the Keeper. Just as Finn started to get sucked in, Princess Bubblegum pulled out some sort of ray gun. She blasted a green energy beam at the black hole. Just before it collided with the black hole, it formed a bubble around the black hole, the black hole now being contained.
There was one last problem: Flame Princess. She was still under the influence of evil. She charged at Finn, but another energy bubble was shot at her. Princes Bubblegum sent about ten more at her, each bubble surrounding the former.
"This way," she explained. "If she breaks out of one of the bubbles, the next will be more spread out, and her fire won't have as much pressure acting on the next bubble."
Flame Princess turned slightly bigger and her fire now burned green. She burned the first bubble layer, but it didn't burst.
At least, for now, it was over.
