thewayneiac: Note the cross-like marking that emphasizes the coffin-like appearance. Shinji has gone from the womb-like entry plug straight into a coffin.
Trajan: This shot always intrigued me, is medical technology advanced enough in Tokyo-3 where robots perform all the procedures? Because even with the sheer multitude of hospital scenes I never see any doctors or nurses milling about.
NemZ: Is it possible they were intentionally isolating him because they feared angel contamination of some sort?
Additional Commentary
Xard: There's this Finnish classic rock album titled "From Womb to Tomb"... :D
thewayneiac: Is that album about socialized medicine?
