In one of the emails between Shaun and William M. it says

"I don't know what you've heard about this place, but there will be a lot here to show you that I know you're going to love. Lots of history."

For some reason this seems like an odd comment to send to some distant email buddy. This anon is requesting that a past Shaun/William with a current Shaun/Desmond where for the team and William meet. Oh yeah, William is Desmond's long lost daddy.

Awkwardness ensues.
