With Angel and all, I could imagine the saving or protecting of a Siren child is possible.
This would be fun and interesting to me.
Especially with what is revealed at the very end of the game. Won't say as I don't want to extend the spoiler tag to cover it (that and I JUST got there myself and beat it tonight lol).
I kinda wonder if there is any real family connection to all the Sirens... I mean, its a special gene that pops up. Now, unless they are throwing the normal concept of genes out the window (totally possible, its a video game after all) then meh. But if they haven't, then it means that Lillith, Maya, and Angel are all related by some distance relative. Part of me wants to see more backstory dropped on us for Pandora and the universe that it exists within (as both playable Sirens came to Pandora from other planets).
so, i read this, and came with a simple answer. now you don't kill angel at the beginning of the game so it is assumed she is still a siren. 4 players playing as a siren, then lilith, and angel. now, idk if that is why they chose 6 or not. just an idea.
