we are on totally the same frequency! i was thinking of almost like gravity falls with a twin peaks twist. darker scary and less silly. I am also currently wrapping up on season 1 so we'll probably finish around the same time. I did read a synopsis since I really wanted to get something going.
my idea was we play the twins who are now estranged and going to different universities but news of wendy's mysterious death brings them both back. so they have to work through their personal drama while confronting a more gruesome and dangerous gravity falls.
