(Melissa Benoists delivery of, And you were there, warmed my heart so much).
(I didnt catch Steins name in this universe).
With Pablo/Ciscos help, they find Millie, a.k.a.

Iris, in an apartment where shes hooking up with Tommy (a.k.a.
Mon-El), whose father Cutter is Digsbys mobster rival.
Needless to say, both Barry and Kara are unnerved seeing their ex-significant others hooking up with each other.
This episode has a lot of fun playing with the tropes of movie musicals.
Its meta in that way.
Cue: Superfriends, the tap number written byCrazy Ex-Girlfriends Rachel Bloom.
Its the most Rachel Bloom song ever.
Its a clever and cheesy but self-aware ode to friendship that made my heart soar.
Unfortunately theWest Side Story-esque war starts as soon as the song ends.
Barry and Kara run out to try and stop it, but they both get shot in the crossfire.
I personally liked the twist that Music Meister actually had good intentions.
With this ordeal over, Kara reconciles with Mon-El and they all return to their Earth.
Barry definitely took a lot away from this latest adventure.
Its the most character driven song of the entire show, and Grant sings it beautifully.
(Also, part of the chorus sounds like John Legends All of Me.)
That being said, this does raise my issues with the conceit of the episode.
I understand the appeal of having Barry and Kara stuck in an alternate reality.
It gave the writers an opportunity to get really meta, which is fun.
It wouldve allowed for the music to be a lot more character specific and character driven.
(Also, Keiynan Lonsdale is a musician).
However, Im very content with the episode itself.
It gave the season a necessary injection of sunshine, which was necessary in and of itself.
