* His lack of reflection: When Jonathan tries to catch a glimpse of the Count in the mirror, he notices that the Count has no reflection. This is the first hint of Dracula's supernatural nature.
* His pale skin and sharp features: The Count's skin is described as unnaturally pale, almost like wax, and his features are sharply defined, with prominent cheekbones and a thin, cruel mouth.
* His aversion to sunlight: Jonathan is surprised to find that the Count shuns the sunlight, refusing to shave during the day and preferring to do so only at night. This is another clue to his vampiric nature.
* His strange, cold demeanor: The Count's manner is cold and distant, and he seems uninterested in Jonathan's personal life. He also has a strange aversion to garlic and refuses to touch holy water.
These observations, combined with other strange events that occur at the castle, lead Jonathan to believe that the Count is not what he seems and that something sinister is afoot.
