Jodi said she went over in the afternoon, after she got off work. She would not commit to what time she got off work, but like you said, if she went in at 10:30 and only worked 4 hours, then she gets off work at 2:30. It is a minimum 25 minute drive from Mimi's to Travis' house (see google maps link:
http://goo.gl/maps/i0gyE), putting Jodi at Travis' house at 3:00 p.m. at the very earliest.
From 3:00 p.m, she had
53 minutes to arrive, go in and help him pack boxes in the attic - she said she was handing him boxes while he took them up to the attic; receive the porcelain angel from him (and didn't he sign it or something), "hang out" and put the angel down long enough to forget it when she left; leave and drive away, remember the angel and drive back to Travis' house, go inside, walk upstairs, and see Travis engaged in masturbatory conduct; freak out, cry, and get back in her car to leave.
Then she called him twice before he responds. And the content of the messages that evening indicate that Jodi was not there at all that afternoon. It looks to me like Jodi called Travis around 4, probably when she got off work, and she did not see him before FHE. I think she went back over there that night after Travis said he couldn't talk.
