A/N: I originally wanted to write the canon universe portion of Two Worlds, One Love in the same timeline as the anime series and make it fully half the story, however that proved to be too difficult (especially with Trowa's disappearance and amnesia). Instead, it ended up in that formless void of dead time where so many fics seem to take place, and played a smaller part. But there was a portion of the story directly involving the events of the series that I didn't want to leave unwritten: Treize's death.

This fic starts in the middle of episode 47. The dialog has been directly pulled from the anime series, though it's been modified and a lot has been added in order to make things make sense in the context of what happened in Two Worlds, One Love. The first chapter is basically an altered summary of the end of the series.

Two Lives, One Death

Duo, Trowa, Quatre and Wufei gazed down at the wreck of the Peacemillion, lodged in Libra's main cannon. The main threat had been neutralized, but the mobile dolls remained. Quatre was relieved to hear from Sally that everyone aboard was all right.

"We'll board Libra and take it from within, destroy the mobile doll system, and demand the White Fang's surrender," Quatre promised her. "And we've got to find Heero and Relena."

"So we're going in? Great!" Duo exclaimed, then saw Wufei was drifting back - and then he took off in the opposite direction, back towards the battle. "Wufei! Where the hell are you going?"

"I'll leave this to you guys," he said with gritted teeth, and left.

"What's up with him?" Duo asked, surprised.

"Just let him go," Trowa advised.

"It's probably important, or he wouldn't just leave us like this," Quatre said, though he wondered. But there was no time for speculation - they needed to finish this before things took a turn for the worse. "We should head for Libra."

"Treize! When I'm done here..." Wufei shouted as he fended off the mobile dolls attacking him. He didn't need to save up his anger; he had plenty to spare.

"Wufei. What are you doing here?"

"Don't play dumb!" Wufei accused him as he cleared a spot atop one of their battleships. Treize followed, curious.

"I don't know what you're talking about," Treize answered, which only served to make Wufei angrier.

"You know what you've done!" Wufei shouted as he took a shot at Treize; he was forced to return fire to defend himself.

"I'm afraid I really don't, so please explain." Wufei was clearly angry about - angry enough to return to wanting to kill him. And that meant he was very dangerous, because Treize knew how Wufei got when he was angry; there was no reasoning with him. He'd been lucky when they'd met before, to sort out their issues in this world. If Wufei had not come unarmed, he suspected he might have suffered from quite a bit more than just a punch in the face. But an enraged Wufei with his Gundam?

His plan seemed to have worked. All he had to do now was play along.

"You have bad aim. I'm over here," Treize taunted him. "Are you going to answer my question?"

The only answer Wufei gave was to attack.

"Shouldn't you be worrying about Libra right now? This battle will continue until that threat has been eliminated," Treize told him.

"They can handle it themselves. I'd kill Milliardo myself if I could, but I have to leave him to Heero," he spat. "But you... you cheating bastard!"

Treize smiled. "Oh? Is that what this is about? Milliardo and I? But surely you've noticed that I'm fighting against him right now. And besides... how can I cheat on you here if we agreed we're not together in this world?"

"That doesn't matter!" Wufei howled, and renewed his attack. Treize fought back, but not as well as he could have. It was only partially not wanting to hurt Wufei - he had enough of that in store for him, of a different kind. "Now fight me!"

"You're right," Treize said. "I was wrong. So let's settle this the way we have before," he said, and jettisoned his rifle to bring out his beam saber. "But can you really do this? Can you really kill me?"

Wufei didn't reply, only gritted his teeth and gripped the controls tighter. He knew the answer already - no - but he had to find out. Even if it meant he was wrong. Even if it meant finding out that the worlds were closer than he wanted them to be.

"Even though I'm better than you here, I won't go easy on you," Treize promised.

Wufei came at him.

Treize knew he could not provoke Wufei enough with just that alone; he needed to add something else to the mix.

"Wufei, tell me... why do you fight?"

"Why do you fight?" Wufei demanded back. "How many people have died because of you? Is it to satisfy your ego? How many people have died for you?"

"Do you want me to tell you?" Treize asked. "As of yesterday, 99,822 people."

"What?"

"Lady. How many fatalities today?"

Lady Une's face materialized on his screen -the last time he would see her, if everything went according to plan. "We've confirmed the deaths of 82 of White Fang's forces, and 105 of our own."

"I see. Give me their names later today," he ordered her, looking pained.

"Yes, sir."

"You bastard!" Wufei hissed.

"I remember everyone who's sacrificed their lives in battle. Noventa, Ventei, Darlian, Walker, Otto, Bunt. How could I forget about them?"

"How could you... and what about those you've killed? Everyone else?" Wufei demanded.

"I can only grieve over the lives lost while fighting," Treize responded.

"Then what about Melian? What about her? She fought against your soldiers - and they killed her! You killed her!"

"Then she did not die in vain," Treize said simply, although he didn't know whether Wufei felt that way or not. "So..."

He took a deep breath, and came straight for Wufei. Wufei had no time to think, only to react - to bring his beam trident up and straight through the Tallgeese.

"Wufei..."

Wufei was immobilized by shock. "Treize! How could you?" he whispered, horrified, and pulled back; but it was already too late.

"Wufei... I love you," he said simply. "Now it's up to you to finish this. I told you before that I would end the war for you if I could... and this... this is the only way... I knew how."

"No! No! I won't let this happen! There has to be another way!" Wufei cried out.

Treize closed his eyes, and the world exploded in fire.

Wufei bowed his head and let the tears come as he slammed his fist down on the console. "Damn you... I wasn't expecting to win! If you... if you aren't there..." he tried to swallow the knot in his throat, but there was already another in the pit of his stomach. "How could you do this to me?"

He stayed put as the battle raged, attacking any dolls that came close - until they too stopped. Lady Une declared the surrender of the World Nations and the broadcast Heero and Milliardo's pointless fight. What else was there to do? Though he only watched it with half an eye, he did notice that Heero's buster rifle was missing. If they had any chance of destroying Libra before it fell... searching for it might provide a much-needed distraction, now that the mobile dolls had ceased functioning. As much as he wanted to curl up and go to sleep, to find out what had happened to Treize in the other world, if he was still all right... there were still things that needed to be finished. He took off.

After he'd delivered the buster rifle - just in the nick of time, too - Wufei only stuck around long enough to see Heero destroy the falling block from Libra and come back safely, and then he took off before anyone had time to ask him if he was all right or anything like that. He didn't need sympathy right now. He needed to find a place where he could rest, go to sleep and wake up in the other world - although he dreaded what he might find there.
