When it plays: Andrew Galucki's emotional vocal in "Who I Am" brings together this tender, healing sequence where April tells Miranda that their rabbi patient forgives her and Meredith confesses to Alex that Dr. Marsh made her feel something that she hadn't felt since Derek. To make us weep even more, the creators of this episode threw in a moment where we see Meredith in a red shirt (the one that she met Derek in) turning her head towards an opening door.
