She felt sorry for him. He was stripped away of his childhood from such a young age. It hurt her to even think about it, and it wasn't even her own life.

Zero was so strong, and she didn't know how he did it. If she was sent into PHASe at the age of seven, she was sure to break down.

Seven was sure he noticed the glances or the long stares she sent him. Zero was keen to his surroundings, but not as much as Four. She didn't mind if he thought that she was weird or creepy.

Zero usually kept to himself and Seven did the same. She didn't dislike people in any way, but she just thought talking was too much work.

He didn't really remember his childhood, nor did she. That was something they ended up bonding over.
