So someone else brought him here, and this person is trying to help him leave? But what does leaving even mean in this case? Back to nonexistence?

It's only belatedly that he notices the phrasing, about worrying about living, is strange, almost like this person knew his thoughts. Can he read his mind? And if so, how well? Ankh is more familiar with the concept than most people might be, but what he picks up from other people is often a bit fuzzy.

If you can tell what I'm thinking and you're the slightest bit helpful, you'll answer that.

But aside from that line of questioning that he isn't going to say out loud yet-

"Who is it who took me?" Maybe if he finds that person, he'll get some answers.
