The dimensions.... ....That would be a way to what he wanted.

[Also, she frowns.] ..........it definitely wouldn't, anyway.

...............Leo wanted his daughter back. ........He wanted Ray back.

........And to put Ray back...........he needed the four pieces that she broke into with everything.

[Deep breath now, and-] ........Kurosaki-niisan's sister. Yuugo's friend. Serena. And... ....Yuzu.

...He needed them.

And then he could use the dimensions going back together...to put them back.
