I can't really imagine Asuka wanting help from him, and even so much as to kiss him of all people.
What I meant is that Shikinami is different from Soryu so you can't take elements from NGE or EoE and apply them to 3.0.
Shikinami in 2.0 is more similar to Shinji than she is to Soryu. Both are extremely lonely people, both are afraid of human contact and both tends to run away when things get uncomfortable.
The movie goes as far as repeating twice the same scene with both characters: in the shower with Pen-Pen, in Misato's car looking outside the window.
Think there might a connection between those two? That they're even more alike than they can imagine?
