The sneak peek was intriguing. So the sword that Emma found, the one from her vision, is capable of hurting Queenie without affecting Regina. Meaining that it may be possible for the heroes to kill Queenie (as they are guessing).

And we have the potential Beowulf tie in in 6x13,  which makes the liklihood that this sword in Emma's possession is Hrunting, which is the sword Beowulf used to fight Grendel's mother.

It will be interesting to see if the sword has other magical properties, like maybe that it is capable of hurting "monsters" and evil being, but something else happens when used against a Savior. As in a Savior can not actually be hurt by that particular sword. (just thinking out loud).
