If someone is stood on their own we have even less idea what context the photo was shot in, very easy to be a red herring and send us in the wrong direction.
There are so many people not in "the group photo" it could be anyone that they are paying there respects to, it could be someone who has left and we are tieing up another loose end, maybe Michelle or Grant or Kathy, anyone of these would be reason for Sharon to be grieving. Ian might not be there if he was driving Kathy home from the Airport and crashed, he could be in hospital and Kathy could be dead or vice versa, its a soap and anything is possible. From what people are posting who work in the "Media" they are claiming they don't know, I think they are getting us going in circles and it will be something unexpected. They film six weeks ahead and six weeks from today is Christmas Day, we all know that "The King of Albert Square" (as Jonathan Ross refered to him) is leaving in a big storyline on Christmas Day. Could this be it, could Nana Moon have put us all out of our misery and killed Alfie as her dying act......
.....anything is possible.....
.....it's a continuing drama series.....
.....it's a soap.....
.....and at long last its getting back to its best and everyone is talking positively about it.....
well done KH2 and JY.
