It seems to me that the library isnt' really all that lost?

Some very fun sci-fi concepts in here though, almost reminds me of Braniac and The Phantom Zone from DC comics. Thorne's first real appearance is a suitable one for his level of villainous bureaucracy, the idea of turning this library card into a new kind of prison is an idea that's very believable, and I like his bouncing off the main cast. He's not got the camp of Drake, but he's more than a worthy replacement.

The alien design is fun if a bit weird, the makeup and headpiece look like they're meant to match but it's absolutely not seemless, mostly I was making negative comparisons to Chantho with it. It's also a bit strange that they showed up there but not to the department, and the romance(???) with Gryphen was a bit out of nowhere, but hey, those can be easily forgotten or handwaved away.

They also seem to be just pretending that Thorne was here the whole time, and no acknowledging that this is is real introduction, but I can definitely accept off-screen adventures having happened.

Overall..... I think I'm actually starting to really enjoy watching K9
