I think many of us believe that. I know that I do. She will always be a disgrace and no good that she does now or in the future will ever wipe out her involvement in this.
I also think Patrick wanted both women gone- he was probably pretty ticked off that the coffee didn't kill Kelsey, as it would have been an easy frame without a mess to clean.
Then she came down two more times, but couldn't do it. He was no doubt angry because her second and third attempts failed. So he did the deed himself, had her do the clean up, had her bring Kelsey's phone and gun with her to Idaho, and he expected her to bring Kelsey's body back to Idaho with her. He was setting her up- two in one shot- one murdered, the other framed and behind bars for life, while he started a new relationship with another unsuspecting lady who no doubt would have been another woman in Patrick's life for his mother to degrade and insult.
It just amazes me how foolish Krystal was, to even consider partaking in all of this. Did she really believe that she was going to live happily ever after with her cowboy? He didn't want the child she was carrying, that was his, to which she later aborted. Then she finds out later, that not only was he seeing Kelsey, she had a baby with him, to which he appeared to love and be proud of! You can't tell me, she wasn't angry that there was another woman in his life, who bore his child- she had to have been livid.
Then Krystal basically played a game with LE- the childish elementary school game "I know something you don't know!", but refused to talk and lied to LE, until the prosecution agreed to make a deal that she was satisfied with. I've said before and I'll say it again, she's a narc. She's no hero, she is a zero, and even Dan May feels the same way- his comment about "making a plea with the devil" speaks volumes.
