But, it appears as if Alison has left some things behind, as Emily (Shay Mitchell) is nowhere to be seen in The Perfectionists — at least not yet. At the end of Pretty Little Liars, let us not forget that Alison and Emily were engaged, and had just adopted twins. But, just because Emily and the twins aren’t in Beacon Heights themselves, it sounds like they’ll be there in spirit. Talking to TV Guide, showrunner I. Marlene King explained that Alison came to “Beacon Heights because an opportunity arises that she can't pass up. It's very hard for her to leave Emily and the babies, but we will understand as the first 10 episodes play out what's happened in that relationship, why it's happening and why Alison is so far away from Emily."
