Mileven kiss scene queer subtext (El knows)
Ok, we all know how wrong THAT scene felt for both characters and how forced it seemed (despite there being intimacy coordinators).
Purple Rain by Prince is the key in my opinion, but not in the way most would think.
The song starts playing at the flashbacks of their past scenes.
(Ignoring how obvious it is that "you've seen me, the real me" and right after her being shown dressed up with a wig is so contradictory, let's not get into that right now).
I want to give focus to the lyrics here:
I never meant to cause you any sorrow
I never meant to cause you any pain
I only wanted one time to see you laughing
I only wanted to see you laughing in the purple rain
This scene is in those flashbacks:
In my point of view this is Mike's message to El, he didn't want to hurt her, he just couldn't love her (like she wanted, romantically) despite him trying. I think El knows this, she realises right after in the original scene that he does love her in a platonic way, but of course that is not what she had hoped for and therefore her expression.
In S5 she has finally internalised it's not about her, but about Mike's sexuality. Accepting it is the reason she is able to understand Mike and smile at him here:
The next lyrics in the scene go:
It's such a shame our friendship had to end
Purple rain, purple rain x3
"Wait, but those are not the full lyrics" is what I thought.
And that is where it gets interesting, as the song actually goes after the first part:
I only wanted to see you bathing in the purple rain
I never wanted to be your weekend lover
I only wanted to be some kind of friend, hey
Baby, I could never steal you from another
It may be a reach, but I think this is El talking back to Mike. She didn't want to be just some "girlfriend" (his beard) but his actual friend, and the last line is a total reference to her knowing about his bond with Will and it being the reason they couldn't work out as a couple.
And after the song is cut off it actually goes:
I only wanted to see you underneath the purple rain
Honey, I know, I know, I know times are changin'
It's time we all reach out for something new, that means you too
You say you want a leader, but you can't seem to make up your mind
And I think you better close it and let me guide you to the purple rain
El continues to talk to Mike with these lyrics, she wants him to know she (in a way) allows him to be himself and go after what he truly wants deep down (Will).
Mike is called "The Heart" (Will calls him this while El is listening in S4EP8), but he doesn't act like it, not at all in all of S5. He lacks leadership because he is always indecisive between being himself and being what society expects from him.
Let me guide you. El and Mike have such a strong (platonic) bond, of course she would want him to find himself, and maybe in her mind that includes him losing her.
I know this is just an interpretation, but I really do think it could fit into perspective and personally I prefer to see it that way.
