Realize that this witness' testimony of loud talking/arguing at circa 2 AM (is it?) for an hour is in stark contradistinction to OP's Bail Affidavit.
In that, he alleges that he and Reeva went to sleep shortly after 10 PM and he did not get up until circa 3 AM to get the fan when he allegedly heard the sound in the bathroom.
From the Bail Affidavit:
"...By about 22h00 on 13 February 2013 we were in our bedroom. She was doing her yoga exercises and I was in bed watching television. My prosthetic legs were off. We were deeply in love and I could not be happier. I know she felt the same way. She had given me a present for Valentine's Day but asked me only to open it the next day.
After Reeva finished her yoga exercises she got into bed and we both fell asleep.
I am acutely aware of violent crime being committed by intruders entering homes with a view to commit crime, including violent crime. I have received death threats before. I have also been a victim of violence and of burglaries before. For that reason I kept my firearm, a 9 mm Parabellum, underneath my bed when I went to bed at night.
During the early morning hours of 14 February 2013, I woke up, went onto the balcony to bring the fan in and closed the sliding doors, the blinds and the curtains. I heard a noise in the bathroom and realised that someone was in the bathroom..."
