Talk:Children of Gabriel/@comment-37472746-20190522010215/@comment-27794543-20190522011459

There were three lines in the last episode regarding the old man:
 * "When the old man see this, he will come back to us."
 * "Isn't that what the old man would've wanted?"
 * "Let's see the old man reject us now."

The old man left them and their actions are what they think he would've wanted – so we can rule out Russell.

To be honest, based on their group name, I'm thinking the old man is Gabriel. "Old man" is slang for "dad" and "Children of Gabriel" also imply parent-child relationship (not that he's necessarily the father / paternal ancestor to all of them). There are religions that refer to their god as 'Father', so I'm thinking it's this type of relationship.

As for coming back to them, it seems that reincarnation is a common theme on this world. The Sanctum Citizens believe the Primes represent the original Primes, so it's not a reach that the Children of Gabriel think that their founder can come back to them. The Sanctum Citizens refer to Gabriel as a demon, so obviously he's no friend of theirs...
