We’ve already seen Matt Ross’ Dr. Montgomery making a cameo in a recent season, so perhaps the whole Infantata plotline will get resurrected and ported over to Season 8.
Had Season 8 taken place at some point in the past, that would have been one thing; and one that we would have been used to, since Season 1 utilized multiple flashbacks throughout.
Actually, I’m quite curious about how Murder House is even up for any kind of a crossover season, considering almost all of the major players from that storyline are dead.
