The man in the picture is Solomon Kane, not Kent. Some of you might have seen him at the back pages of Conan, and he is Robert E Howard's creation, just like that famous barbarian. And just like Mr Kent, he was a witchhunter and demonologist to name a few of his professions, but he never turned evil.
I don't know if it was a hat raise to Mr Howard, or if they made a mockery of his creation, because I'm pretty sure that a large part of Sleepy Hollow's audience haven't read the books, or the comics nor watched the movie. And I'm not sure how he would had reacted on seeing pretty similar copy of him walking in another man's series.
Anyways, I liked the fact that they are turning the wheels and not feel so horribly lost at the aftermath of Moloch's demise, even if they had to but another face in the series. What I don't understand and it's bucking me is Captain Irving resurrection, and his travels on Earth. Why would it have happened if nobody wanted it. The only logical explanation to me is that purgatory has been damaged and it doesn't accept souls any more. In other words I could even claim that they have placed "Closed for business" placard at the front yard.
