Alias season 2, episode 3
Original air date: October 13, 2002

Sydney informs Assistant Director Kendall that the camera they retrieved from Fordsson was actually an early prototype and the real camera is about to be launched into space by the Asiatic Space Agency. Their new client, Sark, is paying for a launch of the satellite so that he can locate a music box made by Rambaldi. Sydney sneaks into the ASA launch site to attach a transmitter to the satellite that will allow SD-6 and the CIA to see the satellite feed as well as Sark.

Sydney visits her mother again to find out what it is that Sark's tracking, and that's when she finds out it's the Rambaldi music box. Derevko tells her that the music box plays a piece of music which contains an equation for zero-point energy (massive energy source). The music box will have to be activated with a code, though. Derevko reveals that Sark was working on cracking the code before she turned herself in. Vaughn remembers that in Will's statement to the CIA, he mentioned seeing Sark working on a laptop on the cargo plane to Taipei. Vaughn has Will hypnotized to recall the memory, which consists of names of Russian authors, which Derevko is able to translate into the code that will unlock the music box.

Sydney and Dixon lead a team to Siberia to recover the music box. Sydney goes into the ice caves alone to retrieve it, and she's able to allow the CIA record the piece of music while she's radio-silent with SD-6. Unfortunately, during her radio silence, Sark and his operatives come up from underneath the ice and kill the other SD-6 agents. Dixon's trying to warn her that Sark's there, but she's still radio silent. She destroys the music box by spraying a corrosive on it so that it won't play, but just as she's finishing that, Sark turns up. He takes the music box and is about to kill Sydney, but she hurls an ice pick into his leg and distracts him. On her way out of the cave, though, she falls through the ice, which refreezes in four seconds. We'll leave her there till next episode, but first, let's tie up some other loose ends:

Someone's messing with Arvin Sloane. First, he notices that Emily's garden is not dead but in full bloom, even though no one's been tending it. Then, he receives a phone call at home that has only high-pitched static on the other end. He has Security Section do a trace on the call, and they tell him it came from a B&B in Sonoma County, a place that he and Emily loved to visit and to which they were planning a trip when she died.

Meanwhile, Jack's agitated about Sydney's increasing dependence on her mother for information and the trust that seems to be forming between them. He asks the CIA psychologist for help in devising a strategy that will keep Sydney away, but she refuses, telling him she's not in the habit of helping fathers manipulate their daughters. Jack tries to pre-empt Sydney's going to her mother for help on the map mission by giving her the fake map and telling her her countermission, circumventing Vaughn in an attempt to keep Sydney from talking to her mother about the mission. Sydney sees through him and gets Derevko's help anyway. Jack then visits Derevko himself and warns her that if Sydney gets hurt by her, he'll kill her. She cryptically responds, "You haven't told her what you did to her when I disappeared, have you?" No response.
