The way that quote was worded, it sounded like it was Snow that was sucked in, but it could well be both of them, and Charming as well (based on another comment above). Which maybe sets up a trip to the EF for the Finale. Maybe everyone around the portal ends up getting pulled in (obviously whoever summoned the portal is unable to completely control it, since that is probably some truly powerful magic).

It is possible that Zelena opened the portal that appeared in the street, and then Emma opens the portal later in the Library to go after the missing people. (since one of the other BTS pics looks like Emma is opening a portal door).
