grayhuze, I think your animation work is excellent, and I have studied Graphic Design. That's not a problem, but I disagree with parts of your theory. I absolutely agree that Jodi was describing her own movements as that of the female ninja. The reason she didn't say much about the male ninja, is that he was non-existent, just there to embellish the lie.
You could be right about the shower door being open, however Jodi could have secretly opened it without Travis's awareness. To me initially Travis just looks like a man taking a shower to decompress and de-stress from the previous stress of her being there. His first sign of shock/awareness she is there photographing him comes at 5:27:18. He is flabbergasted she is there holding weapons on him as well. So he's either seated out of fear or because she disabled him.
I don't believe she succeeded in shooting him first, she may have tried (and that may have been her intention), but the gun jammed. If she had shot him first, he would have been instantly disabled, as Gabby Giffords was and wouldn't have made it out of the shower stall. Instead I think she stun gunned him. There are some still images you haven't included, that I've seen in other rounds of these shots that show white jaggy arcing lines that look like a stun gun firing would to me. I think she did shoot him to finish him off once she got him back into the shower stall, so I believe you are correct that this is where the shooting happened. Just not in that order. (I used to believe the shooting came first). Plus, what clinched it for me is that the bullet casing had to have landed in the pool of blood after the pool had formed, it couldn't have gotten there first, and there is no indication it was kicked there. Lastly Dr. Horn corrected his typo mistake once he realized it because there is no physical way the Dura Mater was intact since Travis was shot. (I was a Speech Pathologist before I got into Graphic Design and I have studied brain anatomy and worked with GSW patients as well).
One more thing, recent evidence has been revealed this re-trial about Jodi offering to lend Travis her stun gun to catch the slasher of his tires.
