I just rewatched the episode finally and was able to pay more attention to the dialogue and nuances I missed the first time from being in an utter freaked out, frenzied state.
I got slightly choked up this time during the Xavier/ Erik scenes in his head. Man, that stuff was so powerfully written and if I may get a little personal for a moment with you all, it really hit me in my core as someone who has lately been on a journey of self
re-discovery of overcoming crippling fear and anxiety, and embracing and loving who I really am and letting go of my past trauma's and sadnesses. A huge part of that whole process of it is the art of "letting go" and relinquishing this need to control everything and be someone else and just ...letting the "cold water" wash over you even though its cold and scary and youre afraid you dont know how to swim. Seeing Erik "let go" and remembering the good person he really is and having his best friend at his side hold him as the "cold water" engulfs the two of them really struck an emotional cord with me.
Xavier: Be brave, let the tide pull you back.
Erik (frightened): Its too cold, i'll drown.
Xavier: I have you Magnus, I'll always have you even if i'm pulled under too. Together we will resurface.
I think we all need someone in our lives every now and then, a friend like Charles, to hold us and say that to us.
Just my two cents
