Why did we never get a conclusion to Sherl's storyline?
Title. It's possible this was clarified somewhere and I just managed to miss it.
One of the most interesting things about the Katrielle era was the implication that Sherl wasn’t originally a talking dog. The game and anime kept teasing that there was something deeper going on and the possibility that he was somehow connected to the larger mystery surrounding Kat’s family. They even give him that specific dialogue about "a tower coming down," implying they knew what his backstory was and had it sketched out in advance. But then… nothing.
It’s weird because Layton games are usually so good at tying together their mysteries. We eventually found out what had happened to Hershel and Luke, but Sherl ended up feeling like an unfired Chekhov gun. Was there an intended explanation for Sherl that got cut, or was he always just meant to be a quirky mascot character?
And while I'm at it, what's with the post-credits scene of the game that says 'Kat will return'? Still waiting...
