my thoughts and my thoughs only that this was a house within at least walking distance of the trailer where Misty and others (how many??? just a question I have as if they do exist they need to ALL be questioned) went to party. I would imagine they were all pretty close with "party" being their commonality.
Of course I could be wrong (and at this point I don't think I am "right" per se... but if there were a party house and Misty was at it that night I think I can reasonably predict the cast of characters and why they would attempt to allude any inquiry into their happenings)
