Some things Chuck wants us to know: Hannah wanted to know who Sarah was, because she liked him. Shaw hit on Sarah. Ellie was delighted to catch Chuck smooching Hannah, his "secret girlfriend." Now, Awesome hangs upside-down exercising as Ellie says she can't believe Chuck hasn't told her about Hannah. She remembers him telling her about his first crush: Mrs. Seaver, the mom from Growing Pains. Ellie says Devon used to tell her everything too and wonders if he's keeping anything else from her. He says he's not in a high-pitched, Awesome The Terrible Liar voice so she feels his pulse and says it's racing. He points out, rightly and wrongly, that he's exercising, then deflects by getting her to go talk to Chuck instead.
At Chuck's, Ellie gives a long-winded speech outside the bathroom door where someone's showering. As we all know, when this happens on TV, the person in the shower is never the person that the one outside the door is talking to. She goes on and on about him not telling her stuff anymore, and how she wishes she'd known about "the new girl," and she won't tell Sarah if he doesn't want her to. Hannah comes out in a towel, and introduces herself. Ellie says she's embarrassed, but doesn't leave. Chuck comes back in with donuts and introduces everyone very awkwardly. I know you wouldn't think he could have made that situation any more awkward, but he totally did, especially when he tells Ellie that Hannah's his "close friend -- technically as close as two people can get." Hannah goes to get dressed, and Ellie and Chuck mutually apologize to each other. Chuck's going to make it up to her by making her favorite: his chicken pepperoni. Which it's obvious she does not love. Also: What the hell is chicken pepperoni? Sarah says she's glad Chuck's moving on from Sarah, but his face makes it obvious he isn't really.
Sarah and Shaw are having a very sunny lunch that looks romantic, judging by the way he's eating her dessert and all. She says they shouldn't see each other, and he asks if this is a preemptive breakup. As they talk, we see someone putting a fancy gun together somewhere. She says she has to stop mixing her personal and professional lives. He tells her he gets it, then leans in romantically and says the vehicle in question has arrived. Casey, listening in, "Roger that." Man, poor Casey has to listen in on a lot of personal and professional life mingling, doesn't he. A mean guy threatens a valet, then Casey shoots him with the tranq gun we've been watching him put together. Sarah and Shaw pop him in the car and peel away.
