Did You Know?


Much of the technological computer terminology tossed out during CTU's efforts to stop Nina's computer worm are simply random terms and phrases nonsensically strung together. See more »


Another violation of the real-time format; Sherry asks Julia where the cell phone is, takes off her coat, and then the camera immediately cuts to her in Alan's bedroom grabbing the cellphone. See more »

They won't let you relax for one minute
19 August 2008 | by (Italy) – See all my reviews

The first half of Day 3 was crammed with events, characters and shocks, and ended on a quite discouraging note (Amador heading to Los Angeles with the virus after giving Ramon Salazar a bomb that eventually killed him). The second half starts with the program's trademark relentlessness, taking full advantage of the real time and the presence of Sarah Clarke as one of the show's juiciest villains: Nina Myers.

With Ramon dead and Amador at large, Jack and Chase choose to take Nina back to the CTU. During the journey, however, she asks if she can make a phone call, and by using that trick she activates a computer virus that jams the agency's entire anti-terrorist network. Her terms: unless she's taken back to Mexico, there will be nothing left to save. As for the other manipulative woman, Sherry Palmer, she decides to confront Alan Milliken personally, a choice that might not pay off the way she expected.

This is one of the most tense episodes of the season, the entirety of the running time (well, almost) being devoted to the CTU's attempts to neutralize the computer virus. It's an exercise in textbook suspense that keeps the characters and the viewers alert all the time: relaxing is not an option here.

Additionally, this is the episode where awkward computer analyst Chloe O' Brian (Mary Lynn Rajskub) is allowed her first moment in the spotlight, anticipating her more prominent role in seasons to follow and proving she isn't just a "pain in the ass", as she was described a few hours ago.
