I thought they could have said it was self-defense. It really was, even though Ainsley went a little overboard with it. That said, in the heat of the moment, fearing for your life and your family's lives, it could easily be explained away. Then I thought maybe have Malcolm take the wrap (which I didn't love, but they did initially start with him telling her he did it). I'm not sure I love disposing of the body and making it disappear angle. I do like the show, and they do play the long game, so I'm happy to wait and see. That said, I'm not sure Ainsley has totally forgotten, at least not anymore. Although I'll admit I have absolutely nothing to base that on.
