Is the final way to end the current crisis… Think about this:
the Finale is 45 minute-long
they need to fill it up with something
they wouldn’t reveal the final part of a multi-step plan
it’s either Plan A which more or less fails and then other ones follow
or one of first steps of a huge one
Sit back and don’t get excited too soon. It doesn’t mean at all they must have got Ford back so he completes the circle here. Very little is certain, and the Pines are still in great danger. Yes, someone could die.
