Emotional video but let's not get carried away.
A few things make me doubt this:
1. A couple of spelling mistakes - even if this 'messenger' made this video, I'm sure Michael would have final approval, and he is a perfectionist
2. I always thought he referred to Katherine as 'Mother'?
3. No new information, just an emotional video pulling at heartstrings..
I don't mean to sound negative, but how many times have so called informers been and gone?
I could be wrong and thank you very much for posting.
