[ His first thought is to sugar-coat the situation; but hiding the truth won't do Reim any good, in the long run. Best to get it over with, like pulling off a bandage. ]

I'm afraid so. It's a bad business, and no mistake. The people who brought us here — the "Initiative" — are using time travel to change the past, on purpose to prevail against an overpowering foe, the "United Earth."

[ He pauses, to let that sink in. At this point, Reim should know very well his feelings on such a subject. ]

Things have gone very well, as you can see. The Initiative and their people have all been slaughtered, save for a handful. Still, they cling to the hope that we can change the past and save them. In the meantime, we survive on the Moon, hiding from the United Earth.
