Most liars need to mix a bit of truth in as well as it is hard to continue to concoct lies
We now have:
1. 'Get the *advertiser censored** out of my house' shouted loudly - probably happened
2. Toilet door slammed - probably happened when Reeva stormed away
3. 'If only Reeva had said something I wouldn't have shot' - Reeva probably ignored him asking her to get out of the toilet
Edit: Why wouldn't he shout out 'I'm armed'!
