There is a painting of a 19th-century wealthy industrialist hanging on the wall, complete with mutton chops and mustache. Dobbsey is looking at it.
Dobbsey: Ah, back to painting again, I see.
Brainley (offscreen): Indeed!
Dobbsey moves to the other side of the room. The painting's eyes are now facing the other side as well.
Dobbsey: It's eerie the way the eyes seem to follow you around the room...
The painting's eyes are now rolled back in a show of annoyance. Dobbsey turns and faces Brainley, who is still offscreen.
Dobbsey: ...you mechanized the eyes, didn't you?
Brainley: It's avant-garde!
