Padme & Anakin
Anakin wasn't always the most social of people, but he adored spending time with Padme. He would gladly do anything she wanted to do. And he was intrigued by the firework display on this holiday. And there was good food and drinks. So, of course Anakin was there with his wife.
He had found the two of them some drinks, and settled down on the blanket they had set up to wait for Padme to arrive with the food she had selected for the two of them. He trusted her to know what he liked to eat, she knew him better than anyone else.
Anakin smiled up at his wife, and nodded at her question. "Something patriotic, I suppose. Or, I'm assuming it is because it's the Fourth." He shrugged a bit at this. He wasn't American, so he could only judge whether or not it was American by the fact that it was there on the Fourth of July. An American holiday.
