Jack
The first thing Jack was painfully aware of as he woke was that he was chained to a wall. And that he was naked. Admittedly, in some cases he would not be objecting to the treatment but since he certainly wasn't feeling as if he had spent a pleasurable evening in someone's arms he definitely objected. The former Time Agent held himself still as his senses told him that someone else was in the room with him. Without knowing if they were friend or foe – and he was leaning towards foe on the whole scheme of things – he had no desire to let them know that he had regained consciousness. There were some things he needed to figure out first – like where he was and where the Doctor and Rose were. Once he knew that, he could go about getting himself free.
"No need to fake it, Captain," a taunting voice spoke from somewhere to the left of where he was chained. "So you might as well open your eyes and take a look around."
With a barely repressed sigh, Jack did so. However, instead of facing some strange megalomaniac bent upon world domination he faced an English teenager. He also couldn't help but notice that he was rather pretty. "Hello," Jack said with one of his patented mega-watt smiles, "Jack Harkness. And, just to let you know, I normally don't give just anyone permission to defrock me. But for you, I think I'll make an exception."
"I didn't need your permission to do anything, Captain. Besides, you're just here because I haven't decided what to do with you yet."
"If I might make a few suggestions?"
"Shut it," he snapped, "I can't quite see what they saw in you that they didn't see in me. He called me 'pretty' and treated me as if I were Rose's pet. And then he dumped me back at my home without as much as a goodbye. And yet, from what I've seen, you've lasted for much longer. Are you their pet, Jack? Are you their little love slave? Oh, I can see that you are. It's obvious to me. After all, why would they pick you when they could have had me?"
"Who are you?" Jack asked, dropping all pretenses of flirtation. At the moment, he was deadly serious. "And where are Rose and the Doctor?"
"Oh, wouldn't you like to know?" he laughed, "But it wouldn't hurt to tell you my name at least. I'm Adam Mitchell."
"You're the one with the..." Jack snapped his fingers and obediently the compartment on Adam's forehead opened, "Ah-ha, I see that you are. No wonder they dumped you."
"Stop that!" Adam snapped his fingers again to close the port, "No wonder they...I can easily gag you, Captain. Don't think that I won't."
"Oh, I have no doubts of that. Where are the Doctor and Rose?"
Adam grinned and Jack could easily see the insanity that lurked behind the boy's eyes. Sadly, he decided to notch the teenager up to an annoyance. "Worried about your friends? Sorry, I can't allow you to see them. Might ruin my plans, you know."
"And those are?" If there was one constant about megalomaniacs it was their need to monologue. Vaguely he wondered if they really did get their jollies by telling their arch nemesis (read good guy) about how clever, wonderful, and awe inspiring they were.
"Simple. I plan to erase the Doctor from time itself."
'Cue insane laughter,' Jack thought as Adam proceeded to do just that.
