I just started watching Evangelion on Netflix and the series explained that pilots' lungs become filled with LCL when in the entry plug of an Eva Unit, allowing them to breath and sync with their units.
However, it never shows or explained why they don't need to pump the LCL back out of their lungs upon exiting a unit. Is it just implied? Do their bodies absorb the LCL through their lungs? Is it assumed they just cough it up? Is there an explanation that I am missing?
Please Note: I haven't finished watching all of Neon Genesis Evangelion, so if this is a major spoiler please warn me via comments and/or use Spoiler Markup.
