Noey MORGAN is obviously there making with all the galaxy themed decorating and kept telling her Nebs that it was a great party. She gave Carol an IOU hologram of her choice and hung out with everyone. She probably made Marty dance with Groot.
KATE came with LOCKHEED he hung out with Chewie and Groot talking shit that Quill probably overheard. She brought Carol a cat charm for the bracelet she got her for Christmas.
