SHINJI:“What do you mean you don’t have anything---?”
Rei and Shinji,
Rei stands up suddenly, as if to interrupt Shinji.
REI (While getting up):“It's time.”
Rei (At the end of the cut):“Let's go.”
Kendrix: Shinji is shocked that she would say such a thing, and perhaps even feels reminded of his own situation. As we see later, her words had a considerable impact on him. Perhaps he doesn't think that a person he considers strong and admirable deserves to feel like he did.
