My guess, it turns out that the combination of hexenbiest+crossing over into death and back+stick is what enables Eve to go through and she crosses to take on the big bad before it can come through. Nick is the only other person who's been dead and had the stick used on him, so Adalind provides the hexenbiest power to send him through even though she can't go with him. And Sean provides the key bit of information that tells them the big bad has actually just been trying to use Eve to open a portal and is really coming for the hexenchild. Maybe Sean will find out from Dasha that the prophecy says "children," and the baby zaubergrimm is also a target.
