When it plays: Alex totally ignores the dozens of candles in his room as he's looking for his engagement ring. There's a surprise twist — Jo's wearing it! She gets down on her knees to propose to Alex and tells him that he's her home. The Wind + Wave's folksy "Human Beings" adds an intimate pull to the moment. You might recognize the band's music on other shows like Nashville, Hart of Dixie, and The Vampire Diaries.
