Keiko
As Ash and Kaori had their conversation outside, Keiko was struck by a sudden realization.
In truth, this had probably been the case since the re-taking of Pearl, but she'd only just noticed.
My role in this... She thought. Isn't it just over?
This internal question was brought forth by a few facts. First, Keiko barely played a part in the re-taking of Pearl and the Battle for Jade. Second, this new plan didn't involve her at all, and, finally...
At the end of the day, her own failure was why Satsuhiro ended up dying. Keiko, in truth, still hadn't quite gotten over that. And, as long as she was still living with Metsumi and Opah, seeing their saddened expressions every day, she wasn't sure she would.
Now, finally, it had been solidified.
... I don't matter anymore.
