If you're familiar with Lost *SPOILER ALERT* they had flash fowards in Season 5, they had flash fowards too in Season 5 which happened directly before the present timeline.

If the clip of Dark Swan is an episode clip and not a teaser (this is all speculation), I believe that we will have flash forwards or have a time jump to show how Emma ended up in that cell.
