The Dark One says Emma brought the sword to SB to reunite the 2 pieces, but in Camelot Arhur had it. So, obviously it can't be Emma the one who put it in the stone again, I think it was Merlin. Right? He did that to prevent the Dark One from taking it. Emma probably got mad and did... something to him during those weeks. Now she needs a hero to release Excalibur.
