Lets save the world, old friend

William Afton was supposed to be dead.
The fire should have finaly killed him.
..is it so bad that technicaly he reached his goal?
Henry Emily was supposed to be dead.
He let himself die in the fire.
..it should be bad that the thing he worked hard for didn't come true in the end....so why doesn't he mind?
Now united together with new powers, the old friends go along to hunt some demons and maybe just maybe finaly fix William's realitionships with well... everyone. Oh, and they have to save their world now almost forgot about that part.
