what is vampire disease?

There are 2 possibilities: - They inherited his skin-pigment disease. - Ther are not his children.

I do think mood such as happy, depressed... COULD be inheritated. As I learned, there are certain genes in your body can control and can pass out on generations. Let's take Abraham Lincoln as an example, he and his family known for great depression past from great grandparents to grandparent, his parents, uncles, aunt. Almost everyone in his family had history of depresion. However, the living enviroment can affect to your mood, that's for sure. In any case, i can potentially wrong.

I see no reasons recessive gene cant skip 2 generation or more. There're usually at least 25 percent that it will survive and remains for quiet a long time.
