Does anyone remember what Bill said while he was talking with Ford about the equation for Gravity Falls weirdness magnetism? 

He said "You think those chains are tight? Imagine living in the second dimension. Flat worlds with flat minds and flat dreams." 

What in the world did he mean by the whole chains thing? And the fact that he liberated his entire dimension masked you think more about how bad his dimension must have been.

Also I'm going to add that the Bill statue will reveal something even bigger later. We all know Bill isn't gone. However, Alex Hirsch has been talking about bringing Gravity falls back this year.

PLEASE ALEX!!!! BRING BACK THIS WONDERFUL SHOW!!! YOU CAN DO IT, YOU ARE THE ALL POWERFUL GRAVITY GOD!!!
