These thoughts keep me awake at night:
After Misato is shot in the back while helping Shinji get to Unit 01- the elevator closes, she falls over, talks to herself/the deceased Kaji, Rei/Lilith/Adam appears above Misato and then there is an explosion. But if the frame is paused at the right moment- you can see her body is in two separate pieces- however later there is a shot with her jacket in a puddle of LCL. Video for reference: https://youtu.be/63UIBoIF3mY?t=6m30s
I'm confused because one of the SEELE guys seemed very determined to remain alive until instrumentality occurred- He grins happily right before dissolving into LCL- and in the puddle of his LCL, his clothes and what looks like to be many medical devices that were keeping him alive into old age remains. From what I understand- during instrumentality, only living things dissolved into LCL (So SEELE guy had all the medical devices, Kaji didn't dissolve, etc). So I'm wondering why Misato dissolved into LCL because it looks like the explosion killed her. I'm guessing it's possible that her jacket is just in a random puddle of LCL and she didn't actually dissolve- and her body could be off-screen.
As far as Asuka goes- at the end, her and Shinji re-materialize from the LCL as they will to. But she was killed by the mass-production eva units. I would assume that she also did not dissolve into LCL but then why did Asuka re-materialize if she was not a part of instrumentality?
I realize the director, Hideaki Anno, says there are no "right answers" to the meaning of the movie but I am wondering if there are any clarifications to these questions. And please correct me if I'm incorrect on any of the above because I'm sure I have a few misunderstandings :)
