How about Tiff coming back, and there is a fight. Joel dies protecting Lilly, and even though Mia was on the other side, she finally protects her child and escapes Venezuela.
Now here are multiple scenes to explore here
The mother child dynamics. The Venezuelan and Enlighten dynamics.
And then there is the kid and the hybrid dynamics, After all
And he will rise from among his peers, and he will lead them into a new age, and it will be magnificent.
She's a hybrid afterall. Maybe we'll see a rise of hybrids, being accepted by humans and leading them in a war with aliens
Well that's a more likely something which could actually happen, so I'm not writing that!
