Very tempted to ask the follow-up question, but the better idea is to wait.
One question, did Pat and Miel cross paths with him as seniors or after their graduation?
Who exactly is/was Erin's mother? Is she alive? All I remember of Erin's backstory is
1. Raised by a grandmother
2. had a very ugly incident with a summoning (gone wrong or gone right depending on your viewpoint) with Cherry before she (Erin) left the "Show Me" State for Wilmot.
Rain is an interesting choice, but is he monologue-ing then, or speaking to her telepathically?
If it is Rain, do we then believe that Jacqui is her daughter? I don't see any other potential candidates. I would certainly hope that if he's talking smack about Jacqui that part of his future would be Jacqui debating whether to rip his spine out through his rear or his neck. But that's far, far, FAR in the future.
Who are/were Cait's parents? I love Julian's description of her.
