Will Byers and Mike Wheeler....the damn ego (an illusion) and why Kali is a much more important character than most people assume
Many see Kali as the evil sister who wants to convince El to die. Someone who is on Vecna's or Dr. Kay's side... but that's not her. The Mind Flayer, the Abyss, the UD, these are all metaphors, and then there are the monsters (whether Dr. Kay, Papa, the Soviets); they are all those societies that oppress others.
Kali (theophany) is a goddess; her home is the Abyss (a metaphor for darkness). Her manifestation is a snake, the tattoo we see on her neck. Naturally, Hopper doesn't trust her from the very first moment. He tells Joyce this directly. But she shouldn't be seen as "evil," because she's the opposite. She also represents love. She wants us to recognize our true selves. She's of great importance to El, Mike, and Hopper this season. And why?
Kali understands human nature; she knows what everyone is afraid of, and she wants us to face those fears. Here, she did it with Axel. When we face our fear, it can set us free. So it's just as she says. She does the same thing with Mike. A snake, by the way, isn't evil either. It's a part of Kali and also represents transformation, rebirth, immortality and healing. Kali represents passionate love. From destruction, she creates space for new beginnings.
In season 2 episode 7, we can even see her true self (background).
She is the goddess of truth and liberation; she tolerates no illusions. In episode 6, she confronts Hopper (he is as mirror character of Mike) with fear and is ready to destroy his false self-image (ego). We all have an ego (a healthy one, or it's much more about who we truly are—without lies). Hopper represents both. But in the series, the untrue ego (the illusion) predominates. The illusion is quite clear when Mike makes Eleven his girlfriend. He chooses the path of conformity, thereby suppressing his "true self" and lying to Eleven and himself. There are recurring hints of this throughout the series. She is the power that shatters illusions. Kali is not the destroyer of love. She is the destroyer of what blocks love. Therefore, Mike must shed his "impure ego" and return to his true nature—to everything he truly is. That´ s why Hop can´ t stand Kali because the "false ego" is afraid of the truth.
In the Purple Rain scene, El speaks as his girlfriend, but also as what she was from the beginning (her true nature). El can't go back to Hawkins (she would continue being this lie/his girlfriend), and then there's the military.
Mike: You...you have to get out of there! You have to get out! (He's speaking to his girlfriend)
El: None of this will ever end, not if I'm still here. (She's speaking as his girlfriend)
Mike: No, no. We'll figure something out. We'll fight back. We always do. (Mike's fantasy plan)
El: I need you to talk to the others. Mike: No. No. El: I need you to thank them for me. For being so kind to me. And teaching me what it means to be a friend. Mike, I need you to help them understand my choice. (Here she speaks as his girlfriend. Dustin, Lucas, Max, and Will have always seen her as his girlfriend, even though she was something else.)
Mike: But I don't. I don't understand. (He's afraid of losing his safe haven.)
El: I know. But you will. One day, you will. You understand me. Better than anyone. You always have. From the day we met... ...you've seen me. The real me. (Here she speaks clearly as her true self.)
Mike: Please don't leave me, El. Please, don't do this. (Here he is speaking to his girlfriend, his safe choice (conformity))
El says that as long as she lives, Henry will too. Now he's dead, but the cycle must be broken. The only way to do that is for her to leave him.She will then be free, meaning this love, and only if Mike accepts that will there be no new Vecna.The cycle can be broken by Eleven´s death. Because when love is dead (between Mike and Will), there is no military, no Vecna (hate). Because no one is hunting you down, locking you up, and doing all those bad things to you. El says to Hopper, "You protected me, but I'm not a child anymore. I decide, and you have to trust me. You have to believe in me." Love was too strong in the end. Mike had that avalanche in episode 4. The water and the damaged pipe -a true metaphor.
El: I will always be with you. I love you. Goodbye, Mike. (Her true self will always be with him if he is ready to accept it)
Of course she's not dead.
I believe the series conveys a beautiful message, and that's what matters, isn't it?
