No disrespect but why are the plates still discussed? Heather noticed, she mentioned it to Ian who remembered. That’s it.Just trying to sort out things in my mind. Did the defence address Heather’s remark about four matching plates and one odd coloured one? At all? I believe he didn’t, because it wouldn’t have helped his argumentation that Ian’s memory was wrong when another witness remembered the same as Ian.
Innocent: she gave her guests matching plates, a standard set of 4 in AU. She took a presentable plate from her everyday (mismatched?) plates for herself.
Guilty: she distinguished her ‘safe’ plate by using a different colour. Too obvious imho.
Remember, she fed kids, probably their friends, didn’t entertain.
