Spoiler:
*Granted this if from memory but I did read the whole issue. Some things may be out of order but this is what went down in the issue. I also wrote this earlier to a couple friends so just going to copy and paste. *First, the Phoenix voice does not talk in this issue, but Jean is mentioned a couple of times. Cyke worries that the Cuckoos will not be able to control the Phoenix because he says not even Jean could control it. One of the Cuckoos voices this concern, as well.
The artist makes a mistake, too. At one point, when they are talking about Jean, we see a panel that is supposed to be her, but it’s Emma in her white Phoenix outfit from Endsong. The colorists must have realized the mistake because, although it looks like Emma, she has red hair and the white costume is colored red. lol So it’s this weird image of Jean in Emma's Phoenix costume. lol
Anyhow, the Cuckoos are Weapon Plus projects. Emma says that the Cuckoos are not the Phoenix yet. She knows what the Phoenix feels like because it once took over her body. She says it has not yet awakened inside them.
The "World" from Grant Morrison's run is used again, as that is from where the Cuckoos came. Sophie and Esme are referred to as “zombie Cuckoos” by Kitty, and later as “pentium zombie Cuckoos” since Beast discovers that they have nano technology over their bones.
Emma finds that there is a mental block in everyone’s mind, and that is why they never wondered where the Cuckoos came from. Even Jean, as powerful a telepath as she was, didn't know anything about them.
In one panel, one of the Cuckoos says to Scott, "We're not Jean Grey... we're worse.”
At the end, the Cuckoos go to the Weapon Plus project where they meet up with some guy (maybe Sublime?) and talk about their destiny. We see tons of pods with Cuckoos in them.
Sophie and Esme didn't go with their sisters. They went inside the mansion and used Cerebra to remind the other sisters of their real purpose.
So this is what we know: The Cuckoos were created in the World and are Weapon Plus projects. There are more than just five. Emma doesn't think they are the Phoenix now (even though they manifested a raptor), and that it hasn’t awakened inside them yet. The Cuckoos have a purpose designed by their creator. The three sisters do say that the Phoenix is what brought Esme and Sophie back.
The big question is still why the Phoenix is with them and why they are manifesting raptors. I am thinking the Phoenix has come to disinfect them. Emma even says it is easier to fight three little Weapon Pluses than three little Dark Phoenixes.
I'm not sure what I think of this issue yet. It’s a Cuckoo story with a little bit of Phoenix.
