In the pilot, Leroy’s whistling “Whistle While You Work” at the very start of the scene where we see Emma’s eye when she wakes up in the cell next to him. It’s a slower, melancholy rendition, but it’s definitely that song.
Speaking of bears, there’s a scene and I wish I could remember the ep but of course I can’t, anyway, it’s a scene in Granny’s and someone walks past a table, might be Emma, but don’t quote me, (how vague can I be, sorry LOL). There’s a family sitting at a table, on the left of the screen, looks like a father, mother, and a child, and the child is complaining that their food is too hot. They’re totally the 3 bears from the story with Goldilocks.
And I know everyone reckons that bow and arrow is to do with Robin Hood, but I still reckon Rumple stole it from Cupid.
