A shot of the outside of the treatment room. The light shines bizarrely red and bright.
Misato stands alone, left behind in front of the treatment room.
FreakyFilmFan4ever: The wide angle lens and dark lighting now make Misato appear alone and trapped in her situation.
Kendrix: Misato looks rather helpless and small in this shot, standing all alone in the corridor. She immediately rushed down to see Shinji and followed the tray, but she was unable to do anything concrete.
This could tie into her whole conflict in ep 4 where she's uncertain about forcing such a burden on a child - she can't do the 'hard', fighthing part herself.
Maybe the helplessness she felt in this instant was what motivated her to play the little part she could play the best she could by coming up with the entire operation Yashima business.
