From my writing journal, back in November:
Well, crap. What are Jonah and Seth supposed to do? Seth is taking command, even though he won’t be going on the trip to the *OMGSPOILER*. Seth and Susan, by the end of the night, will end up physically entangled, if not romantically. The girl that gave Sol her number ends up being Julia, the witch-in-training. So, Seth will state that they need an expert in the strange, Jonah will volunteer Julia, and Seth will gloat about the phone number once more.
