I liked it. It was a little faster than last issue which is good. And the story moved forward which is also good.
The concept of Phoenix spliting in a billon parts... and reuniting as a healing process is been called before. So maybe the same works for Jean. And we will have all different aspects of jean caming toghether (ghost jean, corpse jean, waitress Jean which seams to be her identity and phoenix jean). The weird dome seams like a gigantic phoenix egg like someone said before.
Even when i think this is good and i love the dedication jean is reciving after years of absense. I think this story might feel a little light in the end. There is a mistery and that´s compelling. But as for now, it seams we are just witnessing a process of ressurection. And that´s it. I guess it´s ok... but then again, there´s no big story behind, just a description of a process... like when you describe your car. We will know how she resurrects from the inside.
[Important] BUT and i think theres a REALLY BIG BUT. This is a LOT to JEAN even when it´s just a description of a resurrection. Because it confirms and endorses the ideas shown on Phoenix Endsong about Jean and phoenix being the same entity. Here she is not being treated like a phoenix host that when she is not around, phoenix just goes and pickes someone else. She is not being treated as a clone in stasis at the bottom of the river, which separates the actions of phoenix from the actions of jean. X-Factor taught us that Dark Phoenix was not Jean. But then again... here we are learning she is one and the same, since Phoenix and Jean ressurrection is the same thing. We are finally having knowledge about the Jean+Phoenix relationship.
So it seems small as a story, just a description, but it means a lot to Jean as a character.
