Back in the OOSSL, Casey and Sarah are talking to Agent Redhead. Casey wants to know what they should do about Jill knowing Chuck's an asset. Agent Redhead doesn't want them to do anything. Since the agent Sarah killed was a member of Fulcrum, Agent Redhead wants to keep Jill around to see if Fulcrum will make a play for her. Sarah tells Agent Redhead that Chuck has real feelings for Jill and wouldn't like them using her as bait, and Agent Redhead says that's why none of them will be telling him.
Chuck walks into the apartment grinning and Ellie tells him she hasn't seen his smile in awhile. He tells her he found some of the answers Ellie thought he was looking for. Ellie makes all sort of assumptions about what his answers were and tells him how special Sarah is and that's why he had to go through all that stuff with Jill so that he could figure out that Sarah's the one for him. Well, except for that whole matter of being CIA and you not knowing her real name or anything else about her. Otherwise? Totally the one. Chuck's phone rings, and Ellie assumes again that it's Sarah. Which is sort of dumb, considering that Morgan probably calls Chuck more than anyone else. But it's Jill. Chuck takes it and walks outside. She asks how his favorite secret agent is. He says he's good other than having to study for a CPR test at the Buy More, and he could really use some help with the mouth to mouth. Jill wonders if his cover girlfriend will get jealous; Chuck says no, that's just a cover. Jill thinks having everything be fake sounds really lonely. He tells her it is, but now that she's here, maybe they can have something real. Back at OOSSL, Sarah's listening in (to Jill's phone? Or Chuck's?) and looking sad -- probably just as much at the loneliness they're talking about as at not being the one with Chuck. Jill likes the sound of that, and Chuck asks about the mouth to mouth again. It's really cute, and I think sets something up for the show that could be sort of wonderful. This is make or break time for Sarah and Chuck, I think. She will have to fight for him or lose him forever. Unless the show makes Jill a bad guy, in which case it will be dead to me. It cannot be that simple. I think there has to be an actual choice here, and if she's bad, that's taken away.
Next week: Chuck will do anything to protect his real relationship, even "treason," according to Casey. And in order to save one girl he'll betray the other. He doesn't show which one he's saving and betraying, but the preview wants us to believe he's saving Jill and betraying Sarah. But it also wants us to believe that Casey's order, "Sarah, shoot him!" followed by her pointing a gun and shooting is at Chuck. The title of the show sort of indicates that's not going to happen. Nice try, preview!
