And finally, about vampires he said:
Mike's had along running plan and while there are vampires in Hellboy, it was supposed to be conspicuous that there were no vampires around. The reason why they're missing, isn't because Mike doesn't like them, Mike love vampires. The Pickens County Horror became the first place to plant the seeds to the reveal that there was something there. We've also got the B.P.R.D.: Vampire series that Gabriel Ba and Fabio Moon are doing, that will also reveal other parts of it. Mike and I recently mapped out a significant vampire story, that will blow the lid off the secret, but its still a couple years away.
