Thinking that LK was merely a “problematic boarder” is naive at best. Granted she was both problematic and a boarder, but on a whole 'nother level in comparison to what we usually consider a problematic boarder to be.
It wasn’t as if she was the client that just didn’t pay on time, didn’t put the broom back, and/or gave unsolicited advice to everyone, she was literally out to “finish the bastard” and said many things on SM prior to the shooting that go beyond general barn drama and problems.
I don’t get the endgame though. So they’d drive him until be broke and then? I mean really, thus far, aside from negative attention (due to their own actions), LK & Co really hasn’t gotten anything of benefit. Sure maybe something will come from the Civil suits, but it isn’t so cut and dry, plus she will also be sued. So I don’t even know that the “winnings” from the Civil suit (or suits) will be all that great? But I don’t know. I also don’t know if it’s tricky because LK really doesn’t have much because it’s likely either in her father’s name/shared with him, or in both names, and it’s obviously her father’s/family money. I don’t know the fine details, but I wonder if this will be at all relevant.
If MB was so whack, they could’ve just said, “you’re whack, we’re going to leave.” Instead of seeing how much they could push his buttons. MB could’ve also done a few things differently, don’t get me wrong. It was 2 people that should’ve never crossed paths.
