Absolutely not! She had mentioned in one of her lengthy gab sessions to someone that she used to often sneak into his house and surprise him in bed. I think that this is what she did that night and found him on the computer. I think the fact that they didn't have sex that night was a good indication that Travis TRIED to keep his distance from her. I even doubt that they went upstairs and slept together until 1:00 pm in the afternoon. I think he stayed on the couch and let her have the bed.
I think that it startled her that he was up at 4:00 am when she got there as this was when she probably planned to shoot him, while he slept. She had to alter her plans at this point.
When they woke up, I believe that she did what was her "go to" practice of seducing him with sex. At this point, I don't think that any of it was about sex, but for Jodi to complete the project she came there for, to kill him. I believe this is partially why everything was so chaotic, because she had originally planned to kill him in his sleep and when this didn't happen, she had to kind of play it by ear.
