The fourth person is Diane.
She happily bounced onto the podium, right behind the Lawyer who made the speech and happily chatted with the Grandpa.
Her eyes keep looking at Grandpa and the girl she hugged earlier.
After a few minutes, Grandpa nodded reluctantly. Diane happily hugged him and slipped away. She bounced in her step as she held her friend's hand and left the hall.
The fifth person was Diane's sister. She handed a document to Grandpa. Her demeanor is polite, and she seems to be a quiet woman. Her eyeglasses hung steadily in the bridge of her long nose.
After a few minutes, she left.
The sixth and seventh person was a pair of father and son. They approached him right after the lawyer gave his speech.
They were laughing and smiling in front of Grandpa but Grandpa's face visibly darkened the more he heard them talk.
In front of the audience, Grandpa snatched the document the father was holding and tore it to shreds.
