About that picture of Travis in the shower with both his hands on his chest, do you think he had been stabbed and that's why his hands were up on his chest?
I thought at first it might, but now I think she stabbed him in the chest while in the seated position. He would have started filling up with blood, grabbing at knife, start coughing, got and ran to the sink, meanwhile she keeps stabbing. He had to get up out of that shower in the first few seconds after that stab to chest or he's dead....so I think she did that first. Look at the pattern of the back....his shoulders have to open forward to allow her that tight, frenzied pattern. You can see he leaned on the sink, hands bleeding. That blood is spurting from his hands, deep wounds. Cough sprays blood/lung fluids from chest wound. I think the knife/slash wounds came to the back at the sink, in seconds till he stumbled away, falling down and crawling in hallway or he used wall to stay half-way upright...smears on wall.
