The interrogation of Marie doesn't yield much except that the symphony will be the site for the deal. Marie only gives up that she is to send that text to Cullen, but she lies and says the text will be "Beatrice," her middle name. Sam asks what dress size she is.
Cut to Samantha entering the lobby of the auditorium in Marie's gown at the symphony. Hoyt loads Steven up on gadgets. There's a pneumatic tranquilizer gun that looks like a really long pen and a concussive blast device that looks kind of like a mobile hotspot. Hoyt will remain in the hotel room in charge of keeping an eye on Marie. Steven assures everyone that he has his place backstage at the symphony figured out. Sam starts to get impatient when she doesn't spot Steven. He assures her over the earpiece that he's fine. Sam then sees him take the stage and... then take his station at the timpani. Really?
Steven plays timpani as he tells Leo and Hoyt to stop buzzing in his ear. Marie is handcuffed in the hotel room with Hoyt and can overhear what's going on. The buyer shows up in Sam's balcony with ten million in negotiable bearer bonds and begins demanding the hard drive. Hoyt taps into Marie's cell phone so Sam can text Cullen. Sean gets the "Beatrice" text and realizes the plan has been compromised. He checks his gun. Sean texts back "A40" to Sam, but there's no visual on him or the drive. Buyer has grown impatient so he snatches the phone from Sam, pulls his gun and tells her to come with him. Steven readies his pneumatic trank and tells Sam to step to her side when the strings come in for the song. She does and Steven scores a direct hit on Buyer. Hoyt sees Cullen's signal is really weak which means he could be underground in the parking garage. Leo, always trying to be first, heads down there and gets taken hostage by Sean. He finds Leo's earpiece and smashes it. Sam gets the drop on Cullen, but he has Leo as a human shield. He produces the hard drive from the trunk of the car and demands his money in exchange for Leo's life. Samantha, however, refuses to negotiate with hostage-takers. Convenient. Steven leaves his timpani station, so you know this is getting serious. He goes up to the balcony to secure the money and slips the concussive blast device into the case. Hoyt asks Steven if Samantha's bluffing as Steven hurries down flights of stairs. Steven says she isn't. Human lie detector!
