Phone confusion - this was subtle, but I think Nel referenced it.
There were three phones.
Reeva's which OP tried to use but couldn't.
His two phones. The white phone stayed in the bathroom and was found and photographed there. His other phone was used in the bathroom to make a call (according to OP he was in the bathroom when that call was made). That happened prior to him moving Reeva. The next time the phone appears is when it was in the kitchen on a charger.
From what I understand, OP says he had that phone in his pocket when he carried Reeva downstairs. He was intercepted on the stairs by Carisse(?) and they then tended Reeva. Then his phone was suddenly on the charger in the kitchen.
Now to my mind, he could easily have put the phone on the charger when he went to the kitchen to find bags or just before he started making the calls. I have, from time to time, used my phone when it was plugged in because I needed to make a call on no battery.
However, Nel takes issue with the fact that he carried his phone downstairs when carrying Reeva. He says that he must have put the phone in the kitchen to charge prior to that event. He doesn't explicitly state, but I believe he was leaving the opinion dangling, that OP must have either gone downstairs without Reeva between shooting her and moving her, or he made the phonecall on that phone from the kitchen, not the bathroom. He was with people or being watched from the time of bringing Reeva downstairs, and nobody seems to have seen the phone anywhere but on the charger. He didn't plug it in in front of anyone, so when did he do that?
I do think sometimes Nel talks about something being impossible where I see it as normal or okay
I do too.
What Nel was saying yesterday was that there are just so many incidents of this in the story that it starts to look odd. Everything had to happen precisely as OP says, no matter how strange or unusual. He had to spend the whole time from moving the fans with his back to the bed - all of it, so he didn't see her move. The room had to be pitch black, to the extent of him covering the light on the amp, so that he could not have seen Reeva. It must be normal for her to not respond at all when he says there's an intruder in the house and to call the police.
She must have taken the phone with her for a perfectly ordinary reason. She must have opened the toilet window for an ordinary reason. She must have moved the magazine rack which, if he shot instantly on hearing that sound, placed her at the wrong side of the toilet room.
Then he must have spent some time walking on stumps around the room, crawling across the bed, onto the floor, onto the balcony, back to the room for his legs, all carrying a gun with this apparent hair-trigger, without it discharging another time.
He must have screamed like a woman. What is interesting about this point is that the Defence never said 'it didn't sound like a woman'. They said 'OP sounds like a woman' and then failed to prove this in any way. They never said that that sound wasn't there, and that the witnesses must be mistaken. Now I've just typed that, that troubles me. It's like on hearing that witnesses heard a woman scream, OP has tried to weave that sound into his narrative.
The bat and gun must sound exactly alike for his narrative to work. I can't remember who pointed out upthread (and I haven't gone back over all the witnesses) that in the whole thing, Dr Stipp was the only one who heard two sets of noises at all. All the other witnesses heard one set, or no bangs whatsoever.
So all of these things, yes, there could be a reasonable explanation, but with all of them together, it starts to sound almost freakish or bizarre. As if he just has the world's worst luck or something for this chain of events to take place in this way.
