And don't forget Grayson Hall playing Magda and Julia in 1897.
As for Thayer David, his playing three characters in one storyline shows what a wonderfully versatile actor he is. He even looks totally different for each part. It would've be fun to see him playing at least two in the same episode. I remember TLATKLS did that during the 1897 storyline. I think she was Lady Hampshire in most scenes (I don't think it was Rachel), but did one scene as Maggie when Count Petofi, in Quentin's body, momentarily found himself in 1969. Come to think of it, didn't several do that during the 1897 story, when Jamison had that dream about being at David's birthday party when David was dying?
