"The lions look real, don't they?" said George Hadley. I don't suppose there's any way—"
"—that they could become real?" (209-211)
Here George echoes the worry that Lydia started out with (60), which is about how real this virtual reality actually is. (Hint: it's really real.) What's tragic here is that Lydia and George both worry about the fake lions rather than the real feelings of their children. It's also tragic that they don't use this nursery to travel to Paris or something. Seriously, if you have a virtual reality room you should have a little fun before you get eaten.
