Something just occurred to me. About your 'vampire waking up hundreds of years later' idea. Why not just have them be bad guys? Taking over the world should give plenty of plot. xD And the whole world is against you pretty soon, so... Not that I want to switch or anything. Just a thought I had. :)

Also, omg they can totally be a badass vampire and werewolf couple. One hell of a twisted couple...but still a couple! :P
