Ziploc .. I believe that it would have been appropriate for the COB to be present at the cc and introduce WM rather than relegating that job to JP.
FWIW, I don't think HC's absence was an accident and I don't think it was his choice to be absent. The BOD would not have made this kind of dramatic move without also having simultaneously reached a conclusion on Harry's future IMO. Based on his absence and not introducing WM, I would say it is at least 4 to 1 that he is on his way out as well. Stay tuned.
