She doesn't seem to get that there's a huge difference between being part-dog and being a puppy... she can't really be that naive, right?
Other than that, though, she's kinda fun to be around. Could be, like, his apprentice or something.
Agatha used to be the librarian at the library his owner owned. As far as he knows, she's dead, and he doesn't have any reason to suspect that their paths might cross again.
She was kinda annoying since she always yelled at him to not chew on stuff and climb all over bookcases and ruin everything... but, really, who wouldn't? She was good at petting, at least.
A dog owned by the man who owned the library she worked in. She doesn't have any reason to suspect he's alive in anyway, much less as... well, not a dog.
He was so annoying, though... she kept having to petsit him and all of her boss' other pets. IN the library! That can't even be legal! She did it nonetheless, though, and Hal made it such a hassle... she spent more time cleaning up after him and scolding him for misbehaving than actually working.
They're the only one allowed to sneak into Dicro's car for pets... they're the only one who gets the table scraps... they're the only one who gets to eat people's homework...
Hal's existence is... problematic.
Everyone treats him like he's some wacky dog, but Hal's hiding a lot... he's got a pretty juicy past, too. The perfect type! Full of darkness that no one knows about... he can definitely work with that.
DOG!!!! HE IS DEFINITELY A DOG. Sure he looks more human, but he acts just like a dog and even smells like one. She has a new doggo friend and no one will be able to convince her otherwise. She also follows him around a lot in Hell College.
