Rosa and Maria
Maria was making the rounds of her party during commercials. Some people watched the Superbowl for the game, some for the commercials, some for the halftime show. Maria just cared about the game being played. The only reason she was rooting for the Falcons was because she loathed the Patriots just that much.
She spotted a woman she'd never seen before. Maria had made the party open to anyone, trusting that between Peter and her friends stupid eruptions would be kept to a minimum. The same for theft of her property. So she approached the woman with an easy smile on her face.
