Just finished watching the mid-season premier of Gravity Falls. So many questions now!
Don't read unless you've seen the episode!
Stanley and Stanfords past is fully revealed. It's another classic story of siblings who were very close growing up and gradually finding their own identities. A slew of new mysteries are brought up in this episode. Stanley getting that strange symbol burned into his back, Mcgukket making reference to Bill Cypher, Mabel worried about her Dipper becoming estranged. Even how Lazy Susan got her lazy eye!. I can't believe we have to wait three weeks before we get more details! dammit Disney! You just love stringing us along you diabolical fiends!!
