"Sharing blood with other vampires isn't rare. But there is always some connection that lingers. I honestly don't know how it would work with different vampire species. Perhaps it would be lesser.

For some, he would never stop knowing where they were. Others, it would fade over time. Still others, it was gone forever.
"Perhaps we would only be more aware of one another. But there is sure to be something."
