I know I haven't done my review of the eppy. It'll be soon. Now that I actually have it to rewatch. ;)
So I was checking out the video when...
After Charlie's boss, Pete is copied by the Leviathan he touches her arm!!!
There's this scene where they clearly show him grabbing her. Dun Dun Dun!!!!!!!
That means they could copy her and use her to get to the boys!!!! Eeeeep!!!! :(
