How about Oscar's accounting of the duvet.
A few days ago he insisted the duvet was always on the bed. The police put it on the ground, no question about it. They tampered with evidence. They moved it and put it on the ground. He remembers sitting on it on the bed when he put his prosthetic legs on. He even went so far as to admit to Nel that the duvet was a big problem for his "version." But he's not worried about that at all because he knows it was on the bed. He remembers.
Fast forward to later that day. Nel confronts him with the jeans on the edge of the duvet and the blood spatter on the duvet, jeans and carpet all in the same area and he says "I don't remember the duvet being on the floor."
Then he says, thinking he's all smart, it probably got on the duvet when I retrieved my phones from the left side nightstand. Nel says no. There is no other blood spatter on that bed. His argument falls flat.
And then fast forward another day or two, when Oscar is speaking about the moment that he was on the bed looking for Reeva and thinking that it may be her in the bathroom, Nel asks him if the duvet was on the bed. Screeeech.... Um, I don't remember. He says, I don't remember this part of the night. Nel tells him that's impossible. You are looking for Reeva in the bed, how do you not know if there is a duvet on the bed that you're looking in. I don't remember. He has no clue suddenly if the duvet is on the bed.
WTF
The only reason he needs to make up all of this ridiculousness is because his story is nothing else but a story.
