Obviously it was possible because it had happened, but Simon still maintained it was impossible. Generally speaking, to travel any place, one had to put some thought into it. Or get kidnapped.
Was it possible people could reach across time and space to kidnap people? Was that it? Did this place need a doctor too? He almost rolled his eyes at himself, but it was helping him to at least get his thoughts in order. He also wanted to tell her that time travel was impossible, but clearly impossible was taking on some new meanings here.
"No," he replied to her question. No, he definitely was not feeling any calmer now. He'd feel calmer when he was back on Serenity with his sister and the crew.
He did note the date she'd mentioned, but even that was ... two hundred and fifty years in his past. This was impossible, whatever she said otherwise. He didn't want to be stuck in an invisible cage, he wanted to go home. Back to Kaylee, back to River.
"No," he repeated. "It's not ... making me any calmer." He turned his blue eyes to watch the crowds for a moment. Clothes, he thought before he laughed. Clothes, from the 1960s on Earth-that-Was. He realized then if he was going to take a job as a doctor somewhere ... how very, very primitive the medicine was going to be. But ... no. He wouldn't be here long enough to need a job. He'd ... he'd be back home, soon.
"Where ... is the ... Welcome Center, did you say?" He turned his eyes back to her slowly, still unwilling (or unable) to believe it all.
