Security has decided to be deeply unhelpful today. She is currently showing them various forms of ID and repeating in a slow, patient voice that she has been here before, there is not more than one of her, and she promises she is not there to assassinate her husband or whatever fool thing has them skittish today. Perhaps she shouldn't drop in while the captain's missing; it seems to make them worse. But she got in before while he was missing...
Miles winces - he can almost hear the crack that would result if he tried such a thing. "Point proven. Um... thank you. I think."
"Probably not," Mark agrees. "It's like breathing, to you. The atmosphere of trust. I have lived my life in a vacuum."
"I wish I could rescue you," says Miles. "I wish I had rescued you. Won't you let me—?"
"I can't. I can't."
"You could have a life," Miles says desperately. "I don't know what you've got now, but life isn't it. Don't - don't just crawl into my skin and walk away. It's damned uncomfortable to wear sometimes, and I'm afraid you'd find it stifling."
"It's not that I don't know what I stand to gain; it's that I do know what I stand to lose. I told you, you don't understand how I'm afraid."
"Maybe not. But isn't this," he does his best to make a gesture encompassing the room, given that he can only move his head, "an unauthorized venture anyway? Is it that much more of a risk?"
"Fine," sighs Miles. "Fine... Look - whatever else happens - listen to Mother. She can teach you to breathe if anyone can."
"Not assassination, if that's what you mean... I've read his book. It was fascinating. I think I'd enjoy talking to him. But it's hard to tell. There aren't many people I enjoy talking to." He pauses, then adds, "Ivan's fun."
"Yes. Ivan, and you. That's it so far. But I might like your wife better if I didn't have to pretend to be you to talk to her. Maybe I'll make the experiment."
"...I feel like I should point out that 'tied to a chair' is probably not her optimal conversational circumstance."
