Lady Layton theories
So I've noticed there are at least a couple other Professor Layton fans here. The next game in the series stars Layton's daughter, which of course brings up the question of how he managed to have a daughter when he's been a confirmed bachelor for the whole series so far.
My silly theory involves a spoiler for Azran Legacy, so I'll put it in a comment.




...So my guess is that she's Emmy's daughter by the original Hershel Layton, seeing as the two of them were last seen together.
