Life beyond Death (гет)

A season two of my own imaginings picking up where episode three left us. Multi chapter series, ideally more satisfying then where E03 left off but without any changes to the 'canon' episodes.
-Dracula finds Life after death to be a little more 'lively' than he expected.
Agatha is dead but not gone, Zoe gone but not forgotten...
A new player has entered the chess game, only Dracula and Agatha have found themselves on the same side of the board as this 'new player' begins making his moves, but why and how? More importantly 'who' eludes them.
