When Alia (Renee Coleman) and Zoey (Carolyn Seymour) are returned to their own time by Lothos, history is reverted to its earlier state. As a result, the LaMottas have no memory of the events of this episode.
Although it is never revealed, it is strongly indicated that Alia (Renee Coleman) and Zoey (Carolyn Seymour) are from Sam and Al's future as Lothos, the supercomputer that runs their time travel project, has far more control over leaping than Ziggy does. They also use the term "Swiss-cheesed", which was invented by Al.
Sam: (to Al) I leap back to people that I know and everything should be great, right? But everything’s wrong.
Al: I think Ziggy has finally lost it.
Al: (to Sam) I’m also worried because I’ve never really cared about anyone you leapt into like I care about Jimmy.
Al: It’s my job to be worried.
Alia: Who are you?
Sam: Who are you?
Sam: You can’t kill me, you’d be killing yourself, Alia. I mean think about it, I only exist because you do and you because of me. If I die, it only makes since that you would too.
Sam: You’re not evil, Alia. Whatever trapped you in time is.
Al: Somehow we-we’ve lost two days.
Sam: What, are you telling me none of this ever happened?
Al: No I’m not, Ziggy is telling the both of us.
Sam: She’s not gone, Al. Alia is not gone.
Alia: Sam, I’m not Connie and you’re not Jimmy.
