There's a gasp from Garrot as he takes the phone back. This is a really well-done train! But the next message from the etch-a-sketch is about as annoying as expected. So he just sighs.

"Yeah, okay, you can't leave." That would cause mass hysteria. "But if you could do anything you want, all the time in the world, what would you do?"

Just the fact that Ten can and is willing to communicate is enough to keep Garrot's very prying interest. It's such a weird situation.
