There was a definite sleepy murmur of protest when Stefan began to stir. It was a rare, precious thing to be able to enjoy a full night's sleep without some kind of interruption (if it was not attempts on his life, it was the nightmares that had plagued him since boyhood) and he could be forgiven for hoping to make the most of that peace while it lasted.
However, beyond the brief, reflexive tensing of his muscles Vlad would not make any effort to hamper Stefan's departure -- in the back of his mind, he might even admit that he had expected some sort of reaction like this if only because the boy's track record with relationships thusfar had been far from stellar -- and rather allow him whatever time and space was necessary.
