Denise (Lauren Lapkus) is the assistant manager at Stuart's comic book store introduced in season 11. She is quite a comic book geek. At first, Sheldon does not like the change that her hiring brings to the store but starts to like her because of her comic book knowledge and her ability to figure out his preferences in comic books. By Season 12, she and Stuart enter into a relationship after he takes her as his plus-one to Sheldon and Amy's wedding.
