Look at the slow motion clip of this. LG’s hands are clasped in front of him. Not in her purse.
In this pic his right hand is just below the ‘square’ white annotation box, not clasped in front of him.
This is the best slow-mo I’ve seen; I don’t / didn’t see in live video but I don’t see this view in pic in live pic either: https://www.reddit.com/r/greatawakening/comments/9cfq5u/loli_cant_stop_watching_this/
I suspect he whispered something like, “I have a note. When you walk away, I’ll put it in your purse...”
