Alaric waits until he is sure that she is in a deep deep sleep before making his way to the walk in closet that will be his home for a while. He falls into a fairly deep sleep himself, a small smile fixed on his face.
Some time passes without anything of real importance occurring. Alaric protects Lillian to the absolute best of his ability. For whatever reason nothing comes for them. He should have returned Lillian a long while ago to the underground sex ring that he took her from. He would have thought that they would come for her by now. A few weeks in he realizes suddenly that he can't protect her during the day. He doesn't know any humans that he trusts nearly enough to take care of her when he can't do so. So he takes precautions and begins training Diesel to protect her himself. The dog takes to the training like a fish to water, and in the interluding Six Months, he is proficient at the very least. Alaric teaches the pup to identify Vampires and growl at them on sight. He makes sure the dog identifies his, Vincent's, and Caroline's scent. He certainly doesn't want to get attacked due to a mix up.
His and Lillian's relationship goes swimmingly. They get closer every day, and he thoroughly enjoys her company...not to mention her skill in the bedroom. How she doesn't get pregnant is beyond him, considering her background. Thank Nyx for birth control. There is still some tension between himself and Caroline, considering his and Lillian's relationship. But they are dealing well all things considered. Vincent on the other hand, seems rather distant. He usually does.
In those six months though, unknown to Alaric and Lillian, or Caroline and Vincent, their enemies are mobilizing and planning. They're coming for her. They're coming for blood. They don't care who gets in their way, they'll cut them down without a second thought. In the dead of winter, shit really hits the fan.
