It would appear that Snowing, Killian and Zelena were sucked into the door. Also, it was informed that Zelena was not only holding that wand but also the dagger as well. It looks like Zelena is still against everyone. Also, maybe this leads to where we have not seen the last of Merida yet. I fear Zelena might do harm again on someone.
Well…in close up pics, it doesn’t look like she’s holding the dagger.
Maybe not on her coat or hand, but hidden by her magic.
