The professor was the bad guy. Er, I think. I mean, I thought that the blonde chick was the bad guy (er, gal, or whatever) when I first saw the setup, but don’t forget that Fred gave the professor her phone number at his request. Then, at Wesley’s apartment, her phone rang with the Arcane Gobbledygook, and a portal opened. Chances are, Angel and Gunn didn’t call her to say, “Hi, Fred, just thought we’d send you back to Pylea!” So it was the prof. Damn, it would have been mroe interesting if it was the T.A.
Yes, but I assume it was a set up. The prof said, “Hey, I hear there’s an interesting volume on crossdimensional asymetrical spacetime vortexes in the library. Check it out for me, will you?” Fred goes to the library, and of course she cracks open the book herself, because who can pass up a book on crossdimensional asymetrical spacetime vortexes? And BAM! Sucked into Pylea.
