Watching today I had a lightbulb moment.
One of my biggest problems with the argument theory has been what would they have started arguing about at that time of the night.
Then this business with the fans comes up. This has given me the most likely very ion of the argument theory.
He says he asked Reeva to bring in the fans and close the doors before she went to sleep. He then woke up some hours later and the doors are still open and the fans out. He then gets angry with her for falling alseep and leaving them. He rants and raves about how she has put them at risk. She grabs her phone and retreats to the toilet (the only place in the room where she can put a door between them) just to get away from the argument. She is not frightened enough to feel the need to call for help but like most of us instinctively takes her phone and feels more secure having it. OP continues to rant at her, look what could happen kind of thing, grabs his gun in rage maybe just to show her what they could face in a robbery, he gets more and more wound up, especially as she removes herself, he follows continuing his ranting and in the must of all the rage and anger he finds himself shooting through the door, maybe not even fully realising what the concequences of this would be. As soon as the shots ring out a calm of rationality comes over him, he realises what he has done. He then goes about gaining access to the toilet just like he has said he did.
The intruder idea us fresh in his head, this is what the whole thing was about anyway so it is reasonably easy to spin the intruder story as after all that was what he was ranting at Reeva about.
The above is pure speculation but for me is the first time I have been able to put together a timeline that fits the boxes for the argument theory.
I still not sure what to believe really. OP hasn't come across well today but as has been said, it can be hard for anybody to look good under hostile questioning.
One thing for me is absolutely true and that is he killed Reeva. Whoevers story is true I just don't feel you can ever justify furring blindly into a closed door in a confined space when you have not seen the threat. For me that is murder. Legally I understand that it is not always so black and white put personally I do see it that way.
On a lighter note, I had to smile today when Nell used Roux's catch phrase 'I put it to you that it can not be'.
I wonder if he did that on purpose!
