Two beings, different universe (we imply in some way that the one is a disciple of, a part of, a break away from, maybe a spouse, maybe a child, some sort of close relationship). They are Alien, but not completely. They are not humans or descendants of humans. However, they seem very human in a lot of ways, we can relate to their discussions with one another. They love each other very much. That is very obvious. They are separated from each other, and miss the “closeness” they sometimes have, but the reasons for their separation are for the benefit of both of them.
