When John Smith is trying to show Pocahontas what a handshake is. He has his hand held out and the expression on her face as she says "Nothing's happening".

Nearly the entire "What A Day In London" number. Pocahontas is causing a big disturbance in London while John Rolfe is exasperatedly saying "Pocahontas, wait!" - trying to keep up with her.
Pocahontas is getting dressed for the ball but walks into John Rolfe's room saying "how do I look?" - only wearing her undergarments.
