Which made me wonder if the other devouring kids also were 'travellers' like Main.

The big thing in this episode, however, was how Lutz started figuring out she's not the real Main, right? This makes me want to know w things:

1.) What happened to original Main? Did she die and Main took over OR did Main, unintentionally of course, kill her?

2.) How will people react to finding out? Especially her parents? Tbh they should have long noticed that this isn't their Little girl anymore.
