This is just crazy to me - all of it, but it does seem that there's a whoooole lot of clouding the issue going on from OP's defence.
For me, it's all about his statement and the map of the bedroom area.
- He woke up and moved on his stumps to bring a fan in, close doors and draw blinds. This takes, what, 1-3 minutes for an able bodied person, maybe 3-4 for him? Either way, he is wide awake - this is not a half asleep, fuzzyheaded person.
- During this series of actions, he was in or very near the bedroom. And at no time at all does he notice she isn't in the bed?
- If his claim is that she got up while he was on the balcony, then being as the balcony is nearer to the bed than the bathroom, presumably he would've heard if not seen her rise.
Yet he says he heard a noise from the bathroom? What noise? Presumably either a door, or a flushing toilet. If a burglar breaks into the bathroom, why would they close the door? And no burglar's first thought upon breaking in is to use the facilities.
Upon hearing the noise from the bathroom, he is in the bedroom? Again he does not look to see if Reeva is there. He then puts on his legs, which must take a moment, and since they're presumably near the bed, places him right there. Still doesn't look. Yells out to her. Doesn't hear a response. Though why he would yell, when she's right there in the room? Why not whisper? Why not gently shake her awake and whisper to call the police, so as not to alert the intruder?
He then goes into the bathroom and shoots through the door four times.
THEN he thinks 'oh wait, my girlfriend'
Absolute twaddle.
