Hmm, I think the most likely theory is that Bill blew up the prison and allowed Gideon and the other inmates to escape. Because I saw him wearing what looked like an army general suit.

So I have two theories, Gideon escapes and joins Ford and Dipper to rescue Mabel and at the end of the episode, the prison is rebuilt and Gideon and the other prisoners are taken back to jail. And two, Gideon joins Bill's army to destroy Dipper and Ford, and once Bill is defeated, Gideon is put back in prison.

So what do you think?
