What is the name of song Kelly sings Emma in that episode degrassi?

You're likely referring to the episode "Time Stands Still" in Degrassi: The Next Generation, where Kelly (played by Melissa DiMarco) sings "The Story" by Brandi Carlile to Emma (played by Miriam McDonald).

The song isn't originally sung by Kelly in the episode, but it plays as Emma tries to process what's happening in her life.

Let me know if you have other Degrassi questions!
