Re: Of Your Mom
Nope, still on the other side of the house: on the right edge of the map, almost off it. Currently William's about at that corner where the edge of the carriage-house meets the main building. The kitchen/back door there isn't obvious because no light's coming through a very thorough barricade; it's not an obvious entrance/exit.
The small door on the barn side of the carriage house was open (and banging) when William passed it, though, so he knows that might be a way in/where a girl, a woman, and a surprisingly dry Peke might have come from, if he wants to go into the house. The barn was also open when he passed it, and no longer has a Bad in (maybe a bad or so, but not a Bad), and he can see the feed shed from there.
Considering it's a ranch and the people were prioritising protecting themselves and their livestock from the Comanche before the vampires happened, most buildings are probably open for investigating, with only the house truly fortified. Bear in mind that Vinny was unleashing Hell around the place for a good while looking for Marina, though: if he didn't get her, she's pretty well hidden.
