How the fukk does evil incarnate all time Castlevania number one baddie, Dracula, have a happy ending?
This season was fantastic overall and certainly a step up from the filler tier that was season 3, although I felt like some of the animation were on Naruto V. Pain level. I would be satisfied if this was the last season of this show we ever get.

alot the bad guys got a happy to bittersweet ending Dracula alive again with the love of his life by his side .Issac look like he go to try and take over the world. Hector lost lenore but is now a free man and can go anywhere he wants. morana and striga lost their sisterhood and home but they have each other and a army of vampire soldiers. It like damn the bad guys actually make out petty good in the end
for all the mass killing of innocent people they did as while as trying to enslave the human race over the series 
again
I legit forgot he was the main protagonist until they separated him at the end lol.
I'm Carmilla of Styria... and 

, but he is the king of Styria now

. Sidenote vampire soldiers and non named vamps were almost as cannon fodder as regular humans
