I agree, Hjbau, I think Emma put the hat in her car. I think the hatter did get transported through the hat only because of the careful placing of the hat on the ground. It was facing directly upward – the same way it was when the EQ and the hatter jumped into it in FTL. I also believed him to be back in FTL or Wonderland because of the quick clip they showed of him making hats when Emma looked through Henry’s book. It seemed to me he was frantically trying to make a hat to transport him. This could be the hat that the Queen of Hearts asked him to make, or it could be a new hat he was trying to make to get back to SB?
