OK... last few pics:
5:29:20 - Infamous shower pic - referred to as last photo taken of Travis. He was sitting in the shower for some reason. I don't think he realized the entire time that she was photographing him. He may not have even realized that she was still in his home. So she took the close-up photo and it's obvious he sees her there. He is sitting in that photo. He is looking straight at the camera. I don't know what emotion I am seeing because I didn't know Travis personally. Disgust? Anger? Confusion?
It is not a "smoldering eyes" photo. He would have done something else with his hands or body for that. In the photos I have seen of him with his friends, he is very animated. Perhaps he realized that she was still in his home at that moment.
I am not sure about the time and date shown because look at this link and see the shots next to one another, third line down and the middle and right shot? One doesn't appear to be time stamped? How is that possible? You asked about that spot? That is the shower drain IMO.
5:30:30 - TA shower pic sitting. This photo appears to be an "accidental photo". This was taken a whole minute later than the close-up shot. He stayed seated after that last photo was taken and he knew she was there, or maybe she had already stabbed him. There is something near his bottom. I don't know if it is his scrotum, or if it is a pool of blood.
5:32:16 - dragging photo. 2 minutes later. Dragging him out of the shower, perhaps?
Anyone else's thoughts?
