Quote gardengal: MM tweeted "TEASER: Tonight I report to work 2 hours after midnight. Shooting some super-secret scenes (to air in mid/late Oct)."
Perhaps it is Chadam related since the airing would be on the cusp of Nov sweeps?
If he is not truly teasing or joking, but is being sincere there are a number of things it could be.
It could be Chadam related since that would be a closely related to the date of the miscarriage. There could be a twist in the story where Chadam work together while making it appear they are at odds. I am not saying that they would be reuniting, as it would be too soon based on the MM interview. I guess some fight turn into love scenes could also be taped.
Another possibility might be Eileen Davidson taping with MM.
One of my main thoughts when it comes to secret taping is involving actors/characters who may be brought back onto the show without word being leaked that the actor/character has returned. If remember Tom Bierdz taped solo and more in private and I believe off site when he reprised the role of Philip Chancellor.
All kinds of speculation could be made here regarding Skye, the ghost of Hope, Phyllis recast, Patty Williams, or any characters on canvas which would prevent leaks from stories with Adam involving Chelsea, Victor, or anyone else.
