"It's probably better if you do," Dias said with a slight nod. "I doubt you could keep the lie up for long, anyway, and the quicker you own up to it, the less suspicious it'll make you look. You can tell him you were trying to put on a show of looking sane for the nurses, or that you thought he was someone else, someone dangerous...anything, really. Or even that you don't trust your real name to people in this place until you're sure of them. I don't think he'd question those sorts of motives too much." After a pause, he added, "I don't know what effect it might have on the...timeline, but do you really think he'd never find out on his own if you tried to keep this up? Too many people know you as Claude who you might not be able to warn before they meet him, or who might just forget. Unfortunately, I don't think this is a choice so much as an inevitability - so it's best if you just approach it like one, and make sure it happens on your terms."
