A/N Okay another short chapter. I'll update soon again soon, hopefully. By the way, this one focuses more on action, with some romance.

Enjoy!

Disclaimer: I don't own Phineas and Ferb.

They slept in the cave. Ferb scrunched up against the wall, and Phineas and Isabella cuddling up together on the other end of the cave. They didn't start that way of course, it just happened.

The trio were fast asleep, nothing could wake them up. Not even a certain someone falling in. They had been discovered already. Their "impossible to find" cave, had already been discovered. There was something oddly familiar about this person. It appeared to be a girl. Her hood was drawn up tightly, making it hard to see her face. She had dirty blonde hair, it was hard to tell, but a single strand stuck out.

She began creeping through the cave, looking through little supplies there. Within seconds, one began stirring. Her head immediately snapped over to look at him. It was the one with red hair, sleeping so near… her. The girl. It was HER!

Only seeing the two, not Ferb, she crept over towards Phineas. In a second, he woke up. Albeit blushing from the embarrassment of again sleeping near the princess, he immediately jumped up.

"Who are you?!" he asked in a whisper. "And why shouldn't I kill you?" he added semi-threateningly.

She laughed quietly. "Really Phineas, you don't recognize me?" she asked incredulously.

He studied her for a moment, before making a scared look, that was gone after a split second. "… no! It can't be…"

"Yes Phineas. Not only have you not disposed of her" she said, putting disgust on the word 'her,' "but you have also killed a few others. Now, why shouldn't I kill you?"

He was terrified for a second. He had completely forgotten about the possibility of the society finding him. And it was the leader- why wouldn't she kill him?

"Because… because…" he said, unsure of where he should take this.

"How about this? I kill you now and I leave her here for Baljeet or whatever his name was. I'm sure you know who he is by now." she added.

He sighed. One thing he knew for sure, Ferb would protect Isabella. It was a fair deal. To him anyways, he would die to save her. And he was positive she wouldn't be killed. Even if it was just her and Ferb.

He sighed. Without looking away from Isabella, he muttered something. "Fine."

She smiled, obviously pleased with his answer. She brought her small dagger out, and raised it slightly. Beckoning that Isabella, still not noticing Ferb, would hear them, she began to climb up to the ground. He knew that he could just stay there, maybe find another way out or somewhere to hide, but if he didn't get out there in a matter of seconds, she'd come back. And if she did, she would not be happy. And if she wasn't, she'd kill them all. He was sure of that. He looked at Isabella one last time with a sigh, and put all his weapons down. He wouldn't need them anymore.

The irony of this is that if he wasn't saved from that cell, he would be alive longer. The sun was just now coming up.

He climbed up, and looked her in the eye. She had drawn her hood now.

'Probably the only ones who had ever seen her face are dead now' he thought.

She had dark brown eyes, but they looked tough, not kind. She had a dead serious look in them too. Her hair was barely shoulder length. If she wasn't so threatening and scary looking, she'd be really pretty actually.

"Remember, it's not personal, it's just business." she added.

He closed his eyes, expecting the worst, but words came instead.

"YOU'RE DARN RIGHT IT IS!

Then he heard noises, as if blades were hitting each other. It went on for a while, and he actually had to open his eyes just to check he wasn't doing anything.

Instead, he found a shocking sight. It was Isabella using his own sword, the one he left behind, defending him. He found it almost shocking that they were so evenly matched against each other.

She saw him get up, and turned for a moment. A moment too long unfortunately. The leader's blade didn't hit her, it just struck her sword hard enough to knock her down. Phineas watched in horror as the society leader's blade rose up, and she smiled oddly. She muttered something incomprehensible, a threat of some sort.

Isabella glanced off at Phineas for a moment. His sword, that she was using, had rolled to her feet. In an instant be understood. She kicked it towards him, which he somehow caught.

As the other's blade came closer to Isabella, Phineas dove over to place his sword between the two. It worked the way he wanted, and she staggered backwards.

They heard a slight rustling noise, and Ferb popped out of the hole, with his own blade and another. He threw the other to Isabella, who grabbed it and stood up.

The three took their aim at her, and slashed as much as they could. She was too good, a professional after all. Every once in a while, it would seem like they had her, but she would block it or dodge it somehow.

However, she was getting rather tired.

"I suppose it's time for me to go now." she said, in a weirdly powerful manner. Her hand reached to her belt, and she grabbed a little orb-shaped thing. She threw it on the ground, and the air was full of thick gray smoke. And with that, she was gone.
