Reviews! Also, sorry for the slightly late update...yesterday was terribly busy.

When Bulma and Vegeta stepped into the silent house, it was near ten o'clock, and they were feeling especially tired.

"Trunks," Bulma called for him. "Trunks!"

Vegeta listened for a reply, as well. For several minutes nothing came. The oddity of it didn't take long to strike him. Bulma, too, suddenly seemed rather concerned.

"Vegeta, you don't think...he's gone...?"

"Highly unlikely, though always a possibility," he replied.

"Again?" She looked at the floor, and noticed the red drops. "Vegeta, look."

He glared at the gory mess of tracks mixed with undisturbed puddles. "Blood."

"Was he...? We have to look for him! Vegeta!" He shot a sharp glance at her, and she in turn gave him a pleading expression.

Without speaking further, Vegeta walked back out of the doors and took off into the air to search for Trunks.

. . . . . .

Goten was lying out across the roof of his home. The bleeding in his leg had finally stopped, though his pants were still soaked. He opened his eyes, and they burned through the dark, night atmosphere. He sat up abruptly, looking out across the hills and into the trees of the distant forest.

He stood up, and then proceeded to glide through the air with intended speed, all the way to a city that was alive with night owls, stopping on the top of a tall building where the roof was beneath the shadows of the clouds of darkness.

He looked out over the busy streets and crowds. Abruptly, a malicious smile spread across his face. "I've found you."

. . . . . .

Trunks's head whipped to the side, his attention captured by the Ki that he suddenly sensed. He gave a malevolent grin. "Yes."

Without warning, Vegeta landed at Trunks's side. "What do you want?" he asked.

Vegeta didn't answer when he saw the strangeness in Trunks's countenance.

The half-Saiyan escaped the suspicious gaze of his father when he soared off to where he sensed Goten's Ki.

Finally, the two confronted one another on the top of a wide, flat building roof.

Goten's smile lingered as he stared with his blazing eyes at Trunks, who sent his own burning gaze to the rival.

Without warning, Trunks rushed at Goten and hit him with a powerful blow. When his opponent looked back up at him, he smiled evilly and sent Trunks flying with a kick that seemed to be powered by pure adrenaline and insane, Saiyan energy.

Trunks's entire body smashed up against the side of the ledge on the roof, breaking it into tiny pieces. He'd suppressed his energy with amazing reacting speed so that he would simply be caught by the concrete ledge, rather than crashing through several buildings. He stood up, letting the energy flow freely once more.

"I'm impressed," he said.

"As am I," Goten replied. "You can barely bruise me."

"You took the words right out of my mouth. Why do you not let the whole of your power rush through your veins so you can kill me and be done with it?"

No reply came.

From across the building tops, Vegeta listened intently, stunned, remaining motionless in a patch of shadow.

"I don't need to use all of my power to defeat a pathetic excuse for a creature like you."

The muscles throughout Goten's whole body became larger, and tensed up as the veins under his skin bulged, almost ready to break. The steel-and- adrenaline-like surge that flooded through him to his very fingertips enraged his mind, causing him to summon two black energy attacks, with dark purple, electric waves dancing across the surface. He fired them directly into Trunks's face, which sent his enemy flying all the way down to the streets below.

People shrieked and gasped at the sight of a limp, bloody figure, while others stared in confusion or sickened shock.

Vegeta, knowing better than to enter the battle, immediately started to try and find Goku's Ki.

Kakarot. Kakarot, can you hear me?

. . . . . .

Goku, who had just returned to his home with Chi-Chi, Gohan and Videl, paused. He listened.

Kakarot!

Vegeta?

Kakarot, go to Capsule Corporation, now.

Right.

Without telling the others, he placed two fingers to his forehead, and disappeared.

"Goku!" Chi-Chi uselessly cried for her husband.

. . . . . .

When Goku showed up near Vegeta's Ki, his focus was at once absorbed in the rough, startling battle between Goten and Trunks.

Energy summons and violent strikes made the very air shake and vibrate. Now and then he would catch and glimpse of the frenzied warriors, their faces smeared with blood.

"What's wrong with them? Why are they fighting like that? They look as if they want to kill each other!" Goku was shocked beyond the ability reason the situation.

"They do want to kill each other," Vegeta told him.

"Why?"

"Idiot, use your senses. Can't you tell that their energy is different than usual?"

The energy that flooded into the atmosphere from the brutal encounter that raged between the fighters didn't seem as if it was completely controlled. And it certainly wasn't pure Saiyan power. Goku sensed something almost like an infection, as if their vigor was polluted with disease, a natural and yet unnatural flow of illness and malady.

And then the Saiyan realized that to interfere with the conflict between the two impure combatants would mean that the sickness would spread to him.

There you have it. Review!
