In this "spook-tacular" episode we are forced to ask a lot of questions like:
Who is Sarah Wolfe?
What is the Montessi Formula?
When did all the vampires die?
Where are the other Nightstalkers since Hannibal King is in this?
Why is Blade not a "day walker" yet?
How does Thor fit into this story?
And much more!
