"I love you..." Ianto said as his breath was leaving him.

"Don't-" Jack said. The immortals ears pricked as a familiar sound brewed hope in his heart. Between one blink and the next Jack's surroundings changed. Suddenly he was in the TARDIS control room. The Doctor was crouched next to them holding a syringe. He grabbed Ianto's arm and injected the contents into his bloodstream.

"No time to explain," The Doctor said. "I just can't let you become what you will become if he dies."

"What did you do Doctor?" Jack asked.

"Basically?" The Doctor asked. "I injected the anti-virus into his bloodstream. It should take immediate effect."

At that very moment Ianto gasped loudly. "Ianto?" Jack asked.

"Jack?" Ianto said.

"Thank God," Jack said, dropping a relieved and passionate kiss.

"Well, almost," The Doctor said. "Now, you two are going to help me save the world, and Jack's grandson."

"Steven?" Jack asked. "What happens to Steven?"

"Well, hopefully by saving Ianto," The Doctor said. "I've stopped that from happening and you won't ever find out. You'll be very thankful that I never tell you. Just hope that it doesn't happen. I'm hoping it's not a fixed point in time. That would be bad. Very bad. Very, very bad." Whilst the Doctor was speaking he ran around the control panel, doing God knows what. "Right then, off to save the world." The breaks of the TARDIS groaned in protest as it took off.

Jack held onto Ianto, making sure he wasn't jolted too much. "Are you sure you're okay?"

"I'll be fine Jack," Ianto said. "I meant it, you know?"

"Meant what?" Jack asked.

"That I love you," Ianto answered.

"I love you too," Jack said. "Never do that to me again."

"I'll try not to," Ianto agreed.

"Well," The Doctor said. "That might be a little bit easier than you think."

"Why?" Both men asked, looking up at the man before them.

"You know how I said that that was the anti-virus?" The Doctor asked, before continuing on without letting either man answer. "Well it wasn't, I injected Ianto here with liquid Time energy. It's not safe for humans in most forms, except on the brink of death. When you were brought back Jack, you were dead, no matter how much of the Time Vortex was pumped into you, it would never harm you. But Ianto? Ianto was on the brink of death, if I hadn't spent a long time perfecting this, don't ask how - let's just say there are a lot of immortal rats on New Earth right now."

"Wait, Doctor," Jack interrupted the Time Lord. "Are you saying what I think you're saying?"

"If you think i'm saying that I've just turned Ianto into a rat, then that is not what's happened," The Doctor said with a grin. Then he became suddenly serious. "This isn't a blessing Ianto."

"Never thought it was, Sir," the Welshman said.

"I think it is," Jack said. "Not for either of us individually, but together? This is definitely a blessing."

"When you put it that way Captain?" The Doctor said, laughing. "It probably is. But no naked hide and seek in the TARDIS. Anyway, we best be getting outside, allon-sy!"

Jack laughed and helped Ianto to his feet. The couple followed the Doctor out of the doors. Once they were outside, they realised that they were back in the Torchwood 1 warehouse. "Gwen?" Jack called. The Welsh Woman turned to see Jack, Ianto and a man she vaguely recognised. "You remember the Doctor, right?"

"Oh my God!" Gwen exclaimed. "I didn't think you were going to come! I thought you'd abandoned us!"

"Awwhh, would I do that?" The Doctor asked.

"Oh my God!" Gwen repeated herself. She then realised that Ianto should be dead. "Oh my God," She said again. "Ianto! You're alive!"

"Better than that," He said, grabbing Jack's hand.

"What do you mean?" Gwen asked, her head falling forwards slightly.

"Gwen, he's like me," Jack said. "He's like me."

"Like you?" Gwen asked, upon realising what he meant she bounced on the spot. "You don't mean-"

"Oh I mean," Jack said.

"Oh my God," Gwen exclaimed again and she threw herself at the two immortals.

"Right, yes," The Doctor cut in. "This is all very emotional, but we do have a world to save. You! Agent Johnson, yes? You're the ones holding Alice and Steven, right?" She nodded. "Well you are going to release them and bring them here. This is going to be our base of operations, I suppose that's what you set it up for, yeah?"

"That's right, sir," Ianto said. "I like to think of it as Torchwood 5..."

"Torchwood 5?" The Doctor asked. "Bit soon for that, don't you think?"

"Yes probably," Ianto agreed.

"When we are done here," Jack said. "We're going to rebuild Torchwood 3, you got that?"

"That's for the best I think," The Doctor said. "But, we really should be getting to saving the world now..."

The Doctor really didn't like being ignored and that appeared to be what was happening right now. "You mean that Jack?" Gwen asked.

"Yes, I mean that," The ex-time agent confirmed.

Ianto grabbed Jack's face and pulled him down for a kiss. When they separated he said "That is wonderful news, sir."

"Right yes, wonderful, brilliant even," The Doctor said. "I'm not going to kiss you though. But can we get to saving the world now?"
