Ok, random thought here.
Back in the Pilot, when Emma first tried to leave storybrooke, she encountered a wolf that caused her to have an accident. Now, in Lily, she again encounters a wolf (and it does appear to be the same wolf) that causes her to have an accident, which lets her find Lily.
Add to that her relationship with Graham (The Huntsman, who was raised by wolves), her actually seeing Graham's wolf (when no one else did), and that her first real friend in Storybrooke (outside of her family) was Ruby, and her job of tracking down people, and i start to get a sense that Emma has some sort of affinity with wolves.
Any thoughts?
