"Entire sculptures of your family.. That must be a lot of work." Granted, it's mostly Alice imagining that it'd be. It's not like she's ever tried sculpting before, but she's seen sculptures and thought that it must take a long while to make those..

"Do you make those here on the train?"

Although it'd probably be hard to get the necessary material for it, huh? Let alone space, considering the latter is already so limited on the train to begin with..
