I keep up with the show through various recaps I read in other places. Every time I heard recappers refer to Mike being "at Shady Pines", I thought it was just the author making a joke. I didn't realize he and Aunt Viv were hanging out in Sophia's old haunt.
"Shady Pines, Ma!"
"You don't scare me with that any more."
"I hear they were bought out by some Germans."
