While it was cool to see the duo share wins for their ensemble awards, Octavia positively dominated 2012's award season in her own right. She won for best supporting actress at the SAG Awards, the Golden Globes, and the Oscars. You can see Jessica sharing her happiness (and expressing her love!) just before Octavia goes onstage to accept her groundbreaking win.
For the record, Jessica did receive an Oscar nomination, a Golden Globe nomination, and a SAG Award nomination. But since they were in the same category, she obviously didn't win. I imagine she was still over the moon to see her costar and friend take the cake.
