Like the title says, but let me clear up the question a bit.
If a human (lilin) comes into contact with any of the 13 angels (adam), would an impact start? From my understanding, it would, as the angels are Adam's children, and humans are Lilith's children. If something like this can happen, then touching an Evangelion born from Adam would cause an impact, right?
Is this explained anywhere in the manga, anime or movies? I can't seem to remember anything relating to this topic.
