are they due a lunch break soon? I need to nip out quickly but don't want to miss the actual verdict...
My take on it all, based on instinct and info form various different places and OP's character is that they had a huge row and she locked herself in the bathroom to get away form OP and he was pissed off with that so started banging on the door with a bat to try to open it and she screamed to tell him to stop and in a fit of fiery rage he went to get a gun to shoot the lock off and shot her as well.. intent may not have been to shoot her but he did considering the ammunition he used and she may have been collateral damage but if he'd missed her and got in I bet it wouldn't have been for a 'friendly' chat.
I could be completely wrong but I reckon it was something like that .. who am I to say but nothing else makes sense to me
A lot of people agree with you.
