I think there is a general consensus here that the scene in Dr. Lang's lab is one of the most clunky in the history of the series: shrill overacting, ludicrous dialogue, missed cues, clumsy staging (that tiny scalpel being wielded as some sort of threatening weapon makes me laugh every time I see it, just as it did in the previous episode when it was intended as the device to saw Jeff's head - or at least face - off from the rest of his body). A classic of sorts, I guess.
