Meh, not a whole lot disturbing. I do however agree about seeing disturbing stuff in wysteria. Something about not getting a cookie. That was pretty unsettling.
Wizards face monsters. Monsters are not nice. That's why wizards face monsters. When a wizard faces a monster its not for a friendly game of chess over tea. Chances are, depending the creature, the initial plans the monster will have upon facing a wizard will involve some very unfriendly things, especially if they are up to no good.
That's what bad guys do, otherwise, they wouldn't be bad guys.
