Inside the entry plug, the two endure the effects of the speed and water pressure.
SHINJI:“W-we've got to do something......”
UrsusArctos: The script comment is interesting, I wonder how the pilots feel water pressure inside the Entry Plug?
Kendrix: So far Shinji was just a passenger being dragged along & acting all worried, but now that shit has got real, the roles have reversed, & he’s the one thinking of doing something useful.
I’ve always felt that Shinji actually kinda gets to be real cool in this ep but no one noticed cause he’s wearing a silly outfit during it. To be fair though, Asuka must’ve felt the shock more .
