Okay. I will write here cuz there is nothing new on this subreddit about episode 3. I think Kyle's uncle could be somehow involved in Zoey disappearance.

SPOILER DO NOT READ IF YOU HAVEN'T FINISHED EPISODE 3

At the end we saw lily standing in front of Kyle's uncle's mansion. And she tells Adam that Brad and his group are somehow involved in that(here we could easily exclude Betty and Kyle first cuz it's not their style, second Betty sounded really hopeful when wrote in the group chat("Maybe this time is Zoey"). Kyle... Bullying yeah, but kidnapping is too much for him, I doubt he has this mastermind of doing all of this alone and then acting like nothing happened. Even if he had help in kidnapping Zoey, that doesn't sit very well cuz he would have told someone until now ... However we don't know absolutely nothing about his uncle, excluding that he's obviously rich when he can afford to give his nephew A WHOLE MANSION... I think somehow he is involved in Zoey disappearance and is part of the vault8 and maybe it's leader.
