Chuck and Sarah climb in the window of Shaw's penthouse and dig around. Chuck finds a Kama Sutra book, but Sarah finds the safe behind a painting. Chuck can see it, too, when she gives him X-ray glasses. She figures out how to open the picture, but the safe's password-protected. Before she can even attempt to open it, someone's keys jangle at the door and they see a man on the other side of the door (with their X-ray specs). She says it's Shaw and they hide in the closet. They watch the guy open the safe and take what's in it, then almost open the closet when Chuck's shoe squeaks. But he shoots into it instead. Then Chuck and Sarah chase him out of the room and onto the roof. He jumps to the next building, dropping the case he took from the safe. Sarah goes after it, and Chuck flashes to jump to the next building after him. The flashing is apparently not that great, though, because he barely catches the other building and then is hanging by a cord of some type when the guy comes forward and ... it's Justin. He says Shaw's dead and asks if Chuck cares to join him. Sarah shoots from below and Chuck asks her to check his pulse but to help him first, please, since the cord he's hanging onto is slipping. Luckily for Chuck, Bakula followed him and is on top of the building. He helps Chuck up, with a snarky, "Just an analyst, huh?"

Castle. Chuck shows his dad his office, and Bakula wonders why he wasn't here on a computer instead of dangling from a rooftop. He asks why Chuck's still lying. Chuck pretends the government sees potential, so he's an analyst who does the occasional field mission. He excuses himself to talk to Casey and Sarah about the guy on the roof. They don't know who it was, but they got what he was after. A lockbox just like the one Shaw's wife had. It's a spy's last will and testament, a record of the information they kept. For Shaw, it's all the information he has on the Ring, so the Ring likely wants it back. Sarah says that Shaw must be dead, then reads the exact sentiment from Shaw's letter. Chuck says he was wrong, and Bakula comes in then and asks what Chuck was wrong about. Bakula knows the name Daniel Shaw, and that he's a Ring expert. He guesses the lockbox must mean something happened to him, and tells Chuck that the reason spies need that box is because they could die anytime. "This is a bad business. I don't want my family any part of it." I have to congratulate the show on the timeline here, because Ellie's meeting with Justin while Casey's at Castle with Team Bartowski. Justin tells her they've devised a plan to get to her dad without alerting double-agent Casey, but it's going to require some real spy work on her part. She says she's up for it.
