Today at Bethel United Methodist Church in Flint, Michigan - Reverend Faith Green Timmons interrupted Donald Trump during a speech after he became critical of Hillary Clinton saying, "Mr. Trump, I invited you here to thank us for what we've done in Flint, not give a political speech."
Trump responded [over-talking], "Oh, oh, oh, okay - okay - okay, that's good - and I'm going to go back on point now okay (pause) okay."
All the video of this event becomes blurry just prior to this specific time of his speech, however we can still see enough nonverbal detail to note that Trump is sincerely surprised by this sudden turn of events. Note that Trump's mouth opens in a vertically-oriented oval shape without the exposure of any teeth. When surprise is feigned, people mouth's will take on much more of a horizontally oriented oval (or circle) in addition to displaying teeth. Professional actors routinely get this wrong. Trump's surprise was sincere - Reverend Green Timmons' caught him off-guard.
Less visible are Trump's eyelids which are opened significantly wider than baseline as well as his raised eyebrows and an upward contracted forehead. These changes are also consistent with the emotion of surprise.
Note also how Mr. Trump grabs hold of Rev. Green Timmons' hands. This is not only an invasion of her personal space (intimate space) in a display of false intimacy, but it's also is an attempt at dominance (although her a failed one) and a sign of narcissism.
