Ogre (2.03)

After the Curse
During the time where Mary Margaret Blanchard and Emma Swan are transported into the Enchanted Forest through a portal opened in Jefferson's hat, they journey with Mulan in search of the magic Wardrobe that once brought Emma as an newborn into Storybrooke. As they travel, they have to be wary of ogres. Mary Margaret explains to Emma that ogres do not have very good eyesight, but do possess a keen sense of hearing.

Emma is attacked by an ogre, and almost killed, but is saved in time when Mary Margaret fires an arrow bringing the ogre down.
