I think it was probably a split second..and it looked like she was smiling and having fun... although I wouldn't put it passed Asshat to photo shop.. not sure he is that skilled. Asshat uses the split second shots and there may be one where she is honking and really upset.. but it might appear as a smile....and he goes with it.. that is his thumbnail.. the HUMPERS will eat it up with a spoon and he knows it.Her smiling cheek just doesn't look right to me. I saw the video and she was scared, she kept grabbing him as if she was begging him to get her off. I'm going to go watch again.
She is probably motioning for him to come here and rescue her from that machine that her feet are stuck in...desperately signing for help...and the humps think "sweet girl loves the Peloton".
