You're right about that. ConcernedCitize at CTV posted this on 11/15:
It seemed to me at that time that there were a couple of people posting at different venues around cyberworld in an attempt to establish Jason's cover story. Interesting that CC twice emphasized that the trip to Brevard was planned. At this point we don't know that to be true. It could be that he only made that decision on Friday morning. He didn't want to be the one to find the body, so he calls Meredith, tells her (thru voicemail) he's going to visit his folks and asks her to pick up the fax. I wonder if his parents even knew he was coming before they got the call about Michelle's murder. If not, I can see why the step-father was so insistent about getting a lawyer.
The NCSU Homecoming raises doubt about this so-called planned visit, imo. If Michelle hadn't been murdered, wouldn't he have been wrapped up in the Homecoming festivities? It's obvious he's a huge Wolfpack fan, and his years at NCSU were his glory days -- so much so that he didn't want them to end. As for the argument that he wouldn't want to give up Homecoming to murder his wife, well, the same argument could have been made about Scott and Christmas.
