GREAT! here's one i noticed in the 1795 story line.
after (or rather before!) edmund returns from the old house after dealing with Bathia Mapes, Naomi is in the drawing room by the fire, and hears the door open and shut (THAT GREAT SOUND EFFECT-HAHAH) and she comes to the hall and sees that no one is there (they made the sound effect too soon) she is startled, and come out of character with a pensive "ohhhh...." someone must have directed her to stay there, and then edmond walks in with sound effects and all.
I know most of the "famous" ones, but when i find these little unknown gems, i love to watch them over and over.....
