After the credits rolled, we were shown the statue of Bill Cipher, which was introduced toward the end of the episode. Except this time, Bill appeared to be live instead of animated.

Gravity Falls’ big villain, Bill Cipher, is getting his own book written by series creator, Alex Hirsch. And it’s for older readers! Out in July.

Alex Hirsch talks about Bill Cipher, Summerween, Gravity Falls, and which character deserves a 50 Shades of Gray-style spinoff. The Book of Bill is out now.
