I should return the book to Jay since I finally found it.

You know that Jay is in Henesys, right? Take the Lost Book to Jay.

Oh, and I forgot to thank you for your help. If it weren't for you, I would have lost Jay's trust. Jay has a lot of useful books I may want to borrow in the future. Hee hee!

Can't you just do me this one last favor?

You found my book! Thank you so much.

So he did lose the book.
It's a good thing you helped him find it.

Oh, but some of the pages are missing now. Oh well, it won't matter too much. It's an extremely old book, so it shouldn't matter too much. Again, thank you so much for your help.

Jay is in Henesys.

Have you not found the Lost Book yet?
