Are you referring to the doctor in charge of Quon? His name is Itsuki. Mamoru is Hiroko's boyfriend. (sort of.)

Regarding the ending,

Spoiler:

I saw it as Ayato tuning the world and making a new one by recreating the old--a give-and-take amalgam that also (sort of) reconciles the gap between the humans and the Mu. The painting sort of hints at this. Hence, Quon exists in the new world as Ayato and Haruka's daughter, Hiroko and Mamoru aren't Mu anymore--which further gives me the impression that some of the characters of the old world continue to exist in the new one. So in this case, I also assume that it's possible that Maya exists in the new world as Ayato's mother--or stepmother--while Itsuki also continues to exist as his brother. After all, I assume the conditions of how Ayato and Haruka originally met are still more or less the same in the new world. (--something related to Ayato's father meeting Haruka's uncle I think.)
