Hmmm. Maybe it is 11.
Mrs. Zane doesn't officially know, add Harvard prof and you have 11.
What about the professor from Harvard, didn't he know?
How about if Mrs Zane found out and she told Mr Zane?
Shows lay out plots that lead to the next stage. Prof from Harvard would be too random just like Louis's Rabbi.
Rachel's mom would be better because she'd be doing it more for Rachel's sake and it'd make the drama better.
