Relationships are the heart of Once Upon a Time.

Not just true love or the deep bonds between parents and their children.

Friendship has played a major role on the show since the beginning when Snow and Charming's friends stepped up to help them keep their baby safe from the Evil Queen.

Take a look at the friendships we think deserve to be revisited. Need to catch up before the show returns? You can watch Once Upon a Time online anytime!
