Shinji doesn't have to do anything. Kyoko doesn't want anything from him except the steady assurance of him there in her arms, for him not to vanish after something like that, maybe for him not to be disappointed in her for understanding so very little about him.

She certainly doesn't want to hear an apology. Tears pricking at the corners of her eyes, her arms constrict tighter around him.

"It's been this long since I've known you..." Her voice came out after another moment or two, small and thick. "... And you call me your friend, but I never thought... I never even imagined you might be carrying so much." Her head dipped over his shoulder. "I'm sorry. I am."
