"1-She left the house to get a gun out of her car and went back into the house to shoot.
2-You can't leave a situation, come back, and then claim stand your ground. She had several options of retreat and chose not to use them so her claims of being in danger don't stand. Your duty is to retreat first and only use deadly force if you can't retreat.
