Gabrielle: she sent a patronus to her. 'Get over here. Now.'
Nagini: she appeared next to them. "You rang?" She looked down to see her brother. "What happened?"
Gabrielle: "I don't know. He doesn't remember things. He didn't remember me. He was calling for you."
Nagini: she knelt down, her expression softer than usual. That was only used with her brother. She put her hand on his forehead and sighed. She lifted him and took him to the ROR. She laid him down on a bed, as it was now a hospital room. She could always remake the wedding. She took a wet cloth and put it on his forehead. "It's going to be okay, buddy."
