Nerys is so damn uncomfortable right now that she's barely able to process the fact that she looks right in its entirety, not to mention her weight, though the hair is starting to drive her nuts. She plods along the path with Kira, lost in her mind a little, until she realizes what he's said, and stops, frowning at him.

"This is real and that wasn't?" she asks, confused. "I'm not saying you're wrong, but how can you even tell? You think we were all being observed for what we would do on Earth or something?" This has all been so incredibly fucked up, the entire experience, that real and unreal is something that has a completely different meaning to her than it ever had in her previous life or lives.
