This chapter has an exciting plot twist! Get ready for it!

Short chapter but really… sad

"Tell me who the original alien is!" none of the aliens flinched at Jack's yell. "One day that'll work," he muttered to himself more than any of the others, "everyone down!" Jack dropped to the floor, hearing the thud of his teammates behind him, but a few sickening cracks whipped Jack's head around. Ianto was still standing and there was blood flowing from his body. Jack watched him stumble backwards and saw his eyes full of fear and pain as he fell off the roof. Dimly he was aware someone was screaming, and realized it was him. The firing stopped and Jack stood up, shaking with rage.

"You killed him," Jack muttered as he turned to face the aliens. "You killed him!" he shouted again. "If I were you I would be running, because you just killed someone I like, and that is not a safe place to stand." Jack glared at the aliens and saw a flicker of uncertainty cross their faces. "So unless you want me to commit genocide, get the fuck off this planet." The aliens shifted backwards, but it wasn't until a noise echoed into existence did they panic. It was the sound of the universe, the most beautiful and most terrible thing you could ever hear. One by one the aliens shimmered and disappeared until there was only one left, as the blue police box appeared on the rooftop the alien ran, but Jack raised his gun and shot it through the heart.

"Now c'mon Jack, don't be like that." He heard a familiar voice say.

"Why not?" Jack asked hopelessly, "I… I lost him Doctor. He's gone," and with that Jack collapsed to the ground. The Doctor walked over to him and patted him on the shoulder before turning to the team.

"Owen, go inside the TARDIS, someone needs your help." Owen looked startled at being addressed by the Doctor but did as he was told.

"I'm sorry but… have we met before?" Tosh asked uncertainly.

"Right, you don't remember me. Well of course you don't, you were dying and even if you did remember it would mean… well it would mean the end of the world. Anyway, I'm the Doctor. Not Doctor who, just the Doctor." The Doctor smiled.

"End of the world?" Gwen asked,

"Paradox. Tiny machines that were really the future of the human race killed a ton of people. We stopped the paradox, after a year, but you were all tortured to death in front of Jack. Since Jack couldn't die the Master killed you. Horrible but… you really didn't tell them why you were gone?" the Doctor asked Jack, but Jack was staring numbly on the ground. "Anyway, it's all over now. Killed the paradox, everything's right back where it started, no harm done." The Doctor smiled.

"But it doesn't bring Ianto back. Not this time," Jack muttered miserably,

"Jack, the TARDIS is a very powerful and complex machine. Do you really think I would let someone that important to you die?"

Wait… does that mean what I think it means?
