Rei hears him and looks down (as if thinking);
Unit 00 is behind her.
She raises her head again and speaks.
REI (after thinking a little):“Because it’s a bond…”
Kendrix: She needs to pause and think before answering this question. She has probably never thought about it before.. "Because of my bonds" could either mean her ties to all the projects, or something akin to "Because of who I am" - as this and two other instances show, Rei II holds the opinion that people are defined by their experiences and interactions with others.
Sailor Star Dust: In a similar fashion to Cuts 189/191, Rei's dialogue about bonds with everyone strikes me as referencing Lilith's bonds with all Lilin and the rest of creation.
