I'm not sure if you paid attention to this bc I'm sure being there made you think of different things as you read and saw picture/recaps from the event. But there were a lot of pictures of Sam holding the microphone where you could see his fist and it totally reinforced that the WCC pic Cait posted was of her/Sam. I can't post links in theses asks or I'd send you some as an example but they made for an easy comparison. :-)
OK HI sorry this took me so long to answer I wanted to have access to comparison pics before I answered! I didn’t have any like….perfect shots on my phone but these are the best I could find!
