I want to call your attention to how Ms. Hennessey is scratching her neck. This is an example of a pacifying behavior which fits into the general category of an "adaptor" aka a "manipulator". The neck is one of the most sensitive areas of the body. When manipulators increase, it is a sure sign that indicates an increase in anxiety or discomfort. The Vagus nerves run through the neck on their way to the heart, lungs and other organs. Scratching or rubbing one's neck will stimulate the Vagus nerves, slow down the heart (among other things) and thus help to calm a person down. Jacqueline's smile is a nervous smile, albeit a very good one - she see's something which is making her anxious or uncomfortable. If you see people rubbing or scratching their neck, your antennae should immediately go on the alert and try and figure out the source of possible discomfort.
