Ennis continues the interpersonal relationship section of his run, as Constantine ends up in a hallucinatory quest courtesy of Papa Midnite, during his return to America. We also get to see a major flashback featuring several characters from earlier in his run, and even an interesting mishmash of characters from Delano's run showing back up in flashbacks.
This is hardly the best of Ennis's run, but it feels very deliberate, kind of like when David Tennant, as the Tenthish Doctor says goodbye to all of his companions at the end of Russel T Davie's run on the show. Clearly, there's going to be at least one scene left, but it's nice to give him some down time and closure with characters. Even characters he, technically, shouldn't be able to have closure with.
This volume also has the best use of Chas, since Constantine gave him a bunch of money during one of the previous times he was convinced he was going to die.
I understand why some people didn't enjoy this, but I think if you're invested in the character, this is a solid volume. If you're reading this more for the demon and magic focused plots, this is unlikely to be one of your favorite parts of the run.
