And now we can see that, in addition to her other flaws, Monica is one of those women that is pathologically jealous too... Good grief.
The weird stalker chick came out of the blue, so I'm guessing they're going to have her try to kill Monica so she can have Casey all to herself. Then they will be only one "back from the dead" to being a full fledged soap opera.
She was the one that was a stripper and became a ranch hand (because, yeah, that happens) and had a thing with Jimmy. But then she was cool and tough; now they're portraying her as a weirdo.
