Something I'm a bit unclear on regarding the revealed Eden stuff:

SPOILERS, obvs
Are the bodies Miltron and Gaia in, in their flashbacks, the ones they were actually born in, or were both presumably body snatched from someone else? If it's the former, I think it's the first time we've seen Ascians in their "original" meatsuits. I assume Gaia's current body is her own since it's the one she was reincarnated in, right?
