Did you see where she unwrapped something and put it in her mouth right before that?
my guess she shows cough lozenges when she is coughing as if that will stop it, but it can’t stop the cough due to other origin like parkinson’s thus she disposes of the lozenges to hide the fact that they don’t help
concussion and parkinson’s -how many concussions has she really had?
