Eddie Seeks Answers About Alex Stewart on 'A Million Little Things' (PHOTOS)

Everyone's moving forward after honoring Jon in the latest A Million Little Things, and for Eddie (David Giuntoli), that means seeking answers about an incident from his past.

In "Mothers and Daughters," he becomes obsessed with trying to resolve mistakes. It was his sister Lindsay (Sprague Grayden) who got him thinking about what happened to a girl named Alex Stewart, and after a dream featuring Jon, it's beginning to look like he may have been involved in what happened to her.
