Emma Swan: Once I lived in darkness
Out there on my own
Left to brave the world alone
Everything seemed hopeless
No chance to break free
Couldn't hear the song inside of me
Once upon a time
A song inspired them – be brave
They gave me up because my fate
Was as the one who'd save
The world from your dark magic
And the wicked things you do
They placed a song inside my heart
More powerful than you
All the years of running
No, not anymore
I know what I'm living for
I'm no longer searching
Turns out all along
The answer was inside me
With a song
- As shown in the flashback of Emma's childhood, she attempts to sing for a talent contest at school, but a mean girl in her foster home broke her spirit.
- Emma kept the brief recording she made back then, which was the very song inside her heart.
- Emma's magic grew stronger the more she sang.
- It also protects her from the Black Fairy's evil magic.
- It sums up Emma's life up till that point.
