Thinking about it..
If Heather or #5 are the last devil, it means they had to lie about their family :/
Heather said her dad made her kiss her moms body at her funeral (unless she was adopted?)
#5 said she had sisters and they'd go ice skating at their uncles farm on the pig poop (unless she was adopted too)
But they can't be adopted since they've been with Gigi? Unless there's some more twists and turns in the next episodes
I think we know about everyone's family except Pete.
Fun fact: Jennifer was from Antarctica
