It's Jim lee.
the book was probably being written to accommodate for more art.
At least it's not the old Marvel method where the writer would hand over a plot, the artist would draw the comic with blank speech bubbles and then the writer would fill in the bubbles.
Although I recall Bendis at a con saying, "I love Mark Bagley, I totally love him, it's not that I want to write less, it's that I want to see him draw."
Symbiote vs parasite.
Either you have eidtors screaming, or the writer artist team find thier own natural equilibrium.
