I have a theory of what might happen. Ok here it is...
Angel is the one light. And she is from the future. The doomsday group are holding her captive and questioning her about Max... and if they are related. Well, she is not giving them any direct answers, so they go for fang, who is elsewhere with his flock. He gets into trouble and calls max. Dylan picks up the phone and doesn't pass on the message, saying that it was someone selling something. Max freaks out, thinking that they must be after them, and now had her phone number. She gets a new phone, and fang doesn't know.
Meanwhile, Ella is having wings put on her, despite the protest from her mum and Jeb, who was helping the scientist who were studying angel grasp her DNA.
Fang updates his blog, and Nudge finds it and shows Max, who reads that dylan keeps picking up but not telling. She freaks and goes after fang, telling dylan to leave her alone. The flock goes, but max makes dylan stay. he waits a while and goes after them, after foreseeing what will happen if he doesn't.
Elsewhere, Angel breaks free, and goes after max. But she is injured, and stays somewhere to heal.
The Flock and Fang's gang (and Dylan) meet up somewhere and they receive a message from angel for a plea for help. They all split up to look for her in these pairs, after much argument;
Max + Fang
Dylan + Maya
Nudge + Kate
Gazzy + Iggy + Rachet
Kate + Holden
Well, after a long look for angel she is finally found, but by an exhausted dylan and maya. so dylan and maya were going to get a plane back to the meeting spot, after they texted everyone they found angel. they book a plane, but angel want to fly, so she will follow the plane. everyone gets to the set point to meet and as they watch the plane come in to land, it blows up, dylan and maya included. Angel comes soaring in and just says "it had to happen."
everyone is shocked and max makes her tell them what she means. She says that she really can't say, but does eventually let slip that is dylan lived for another week, she wouldn't exist.
I draw conclusion as my day dream ended that Fang was her father, and Max would have chose dylan instead within a week. After all, she is from the future. And gazzy? HE was the in the first generation of the avian human mutants.
