Some background stories are shared as the harrowed group prepare graves for their fallen fellows, two of which can only be filled with memories, the remains of their friends being lost, the state of their souls unknown.
Enter the Red Witch and the Red King. The resurrection of the Red King means the failure of the group, unable to keep the ritual from taking place, and to add insult to injury he is resurrected into Thomas' body.
However, an opportunity also appears with this resurrection, the Red King is now mortal.
I think I've mentioned before that Baltimore is a more bleak worldview than Hellboy, there are very few jokes (in fact, I can't remember the last bit of humor, even black humor, I've seen in this comic). I think that the Mignola, Golden, etc. crew have been moving in this direction in most of their works, from Hell on Earth BPRD, Abe Sapien's new series and Hell Boy in Hell, failures abound, the planet is not saved, the heroes do not come out on top, the monsters win. But, we fight on.
