Most of the romantic relationships in this series remain rather understated, even Saya and Haji's did. Julia tries to get David's attention from the very beginning of the series, and there is always a clear 'thing' between them, but it's only at the very end that it's passingly mentioned that's she's pregnant with his child.

I always interpreted Mao following Okamura to the Middle East as another one of those understated, or potential future relationships. Same with Moses and Karman: Moses cared enormously about every one of the Schiff, but Karman was on a whole 'nother level; running around like mad trying to find a cure, even being willing to kill Kai. He didn't have the Thorn yet, could have chosen to live on with Lulu, and yet he preferred to kill himself rather than live without Karman.

Personal interpretations all over the place, of course. Mao and Okamura always had a nice chemistry, in my opinion: they bicker a lot, yet in the end they stick together (plus, he left his favourite camera with her, that's a pretty big hint, to me). I see her leaving with him as finally giving up her obsession with Kai and going off for better horizons, at the very least. Plenty of possibilities for things to happen there.
