I felt like everything he was facing and discovering as he went through the game worked as buildup. The developers could've done some more with his appearance to illustrate this rather than leave it to Zobek's loading screen thoughts, but I knew that a "dracula" didn't yet exist in the world once I left the cave in the beginning of necromancer land and figured that he might end up becoming Dracula.
At least this seems to give more evidence, along with that random passage found in a knight's journal, that the castle is a dark entity just like the old series. Hopefully this will lead to some great belmont versus dracula games in 3D!
