Adam vrs. Jack
Adam Mitchell ran his fingers across Rose's sleep slackened face and smiled. Once he had told her that it would take a better man than he to stand between her and the Doctor. Soon, provided the device worked as advertised, there would no longer be a 'better man'. Rose would be his and he could show her that he was everything that she needed. "Soon, my love, soon," he told the silent figure on the bed. Rubbing his hands together slightly for warmth, he circled the bed to reach the other unconscious body.
"Ah, Doctor, it's too bad that you're not awake to enjoy this," Adam said, checking the consoles that monitored the two people on the beds. Several silver-clad tubes connected the Doctor's head to Rose's. Tiny filaments stretched into each mind feeding thoughts and projections into each. "You see," he said as he walked around the bed, eying his nemesis, "The interesting thing that I learned about Time Lords – and it was rather hard to come across anything of use, I'll have you know – is that each one carries a bit of the temporal vortex inside their minds. That's how you manage to know about the ebb and flow of time and all that. Interesting, no?" He paused as if he would get a response from either one of his captive audience, "Well, I thought so. You see, I found out that if I could just convince a Time Lord of his non-existence that he could essentially wipe himself from the timeline. Oh, it has been tried before or so I discovered, but no one ever thought to use someone that the said Time Lord cared for as the means of that erasure. That, of course, took my genius to figure out.
"So, Doctor, your precious Rose is going to be the reason why you get wiped from the timeline. Fantastic, isn't it?" Adam grinned. Satisfied that everything was proceeding according to plan, he returned to his other captive. Sadly, Jack Harkness was a bit of a problem. While Adam could cause the indirect death of someone like the Doctor, he could not kill directly. That was far too messy in his eyes; he had seen enough direct death during that episode with the Dalek. He stood in front of the shackled Time Agent and considered him with a thoughtful gaze.
"Come to gloat?" Jack asked, feigning a yawn, "You're an idiot, you know. And to think the Doctor only called Mickey an idiot. Then again, the Doctor never really mentioned you beyond the whole snap on, snap off feature."
"Oh please," Adam said, rolling his eyes, "You think that you're so much better than me."
"That's because I am."
"You're not," Adam insisted, "I captured you, the Doctor, and Rose. Me. All by myself. And now, you're going to get to watch the Doctor join the rest of his species in timelessness."
"Me, me, me. I, I, I. That's all that matters to you, isn't it? And here I thought we were getting somewhere. I felt a connection for a moment - something that hit me right in the gut. Oh, wait, that was indigestion."
Adam actually growled. "I'll have you know..." he began angrily, before stopping, "Clever. Trying to get me mad so I'll make a mistake? Too bad, I'm smarter than that."
"Oh, no. You figured out my clever plan. Damn," Jack said dryly, "I wonder. Have you really thought through these plans of yours? What happens when you get rid of the Doctor?"
"I get Rose," Adam said with a shrug.
"No," he corrected, meeting Adam's eyes, "You die."
"I hardly think you're in a position to threaten me, Jack."
"I'm not threatening you. I'm telling you the truth. You remove the Doctor from the timeline and everyone dies. The Daleks, the Cybermen, the Sonatrans, any one of the species that you haven't even dreamt of in your most horrendous of nightmares will take over the universe. All because of you and your childish wish to get even. The Doctor left you behind because he only takes the best. And you know what? I can't say I blame him if this is what you come up with for revenge. Because, Adam, in the end you don't win. No one does. Instead, the universe loses."
"He's just one man," Adam protested, "He can't have that much impact on history."
"Oh yes he can," Jack said, willing Adam to believe him, "He's the Doctor."
