It's always a sobering experience to see someone in such denial go to such lengths to try to cover it up.
But anyway, I looked up the scene in question that was the impetous for the entire exchange between Rainypark and myself and the only portrait Liz makes mention of in that scene is the one of Jeremiah, which hangs over the mantle (but I think we all knew that). The portrait of "Leonardo" isn't even anywhere to be seen in Episode #2.
In Episode #3, Carolyn explains to Vicki that the bearded gentleman whose portrait hangs over the piano is Issac Collins (who at that point supposedly "began it all" back in the 17th century. Funny how his clothes look far more Victorian than circa the England of King James or even the Puritans. But then, when did DS ever let a little thing like era-inappropriate clothing ever stop them?
And of course, in Episode #4 the portrait has suddenly moved to hang on the opposite side of the window. Apparently the Collins portraits love to play musical walls.
). "Leo" is among the missing again.
In Episode #4, while lecturing Roger, Liz identifies Issac and Jeremiah again, as well as naming the man in the portrait between the cabinet and the fireplace as Theodore and the man in the portrait above the sideboard (where the phone is) as Benjamin. I'm afraid that "Leo" is still nowhere in evidence.
If Sci-Fi decides to run DS from the beginning again, I think a game we should play on the forum is Be The First To Spot Leonardo's Portrait.
