Many have noted a complete lack of chemistry, of physical synchronicity between the Dismals and given SoFail’s EBDs this is not surprising. She seems to be pretty high on the Hare Scale so her mimicry skills are rather poor. Dancing and other forms of allelomimetic behavior in humans are highly dependent on instinctive, non-verbal cues. While psychopaths can imitate basic social behaviors they lack the ability to empathically connect with others. This is particularly evident in their flattened affect, emotionless gaze and stilted physical interactions. Dexterity is something different altogether and no amount of training etc. can give them the basic abilities they inherently lack.
