After a tactical group infiltrates the DSR and steals all the Rambaldi artifacts, CIA director Hayden Chase discovers that the alarms at the DSR were disabled from Nadia's computer, allowing the raid to happen. Mrs. Chase shows up at the apartment to question her. Soon Sloane and Jack arrive and suspect that Sophia, who had access to the computer while she was living with Sydney and Nadia, is in fact Elena Derevko. They follow her trail to a dead Rambaldi follower, a stunning betrayal, and a presumed dead family member when in a surprising twist, Sydney and Nadia learn that Irina Derevko is in fact alive.

Has Sloane turned bad yet again?
21 September 2010 | by (United Kingdom) – See all my reviews

As this episode opens a group raids a CIA facility, kills the guards and makes off with a variety of Rambaldi artefacts. This leads to CIA personnel temporarily closing down APO and searching Sydney and Nadia's house. At first Nadia is suspected because her pass codes were used to access the facility but soon they realise that she had been used by Elena Derevko, the woman she knew as Sophia. Sloane believes that Elena will want to meet Lazlo Drake as he is the one man who knows how to assemble the various parts of the Rambaldi device. In a flash back we see that he and Nadia have met him before although at the time they were still missing a key component so he wouldn't hand over the plans. Sydney locates Drake and accompanies Sloane there. When they get there he is dead but it looks like they will find the information needed from his security system. That is until Sloane knocks out Sydney and vanishes with the information. There is only one person who might know where Elena would be; this means that Jack must pay a visit to Katya Derevko. With the information she gives they are able to track down Sloane and Elena but the operation does not go well and they escape after Elena shoots Dixon in the back. Luckily he survives and has some shocking news for Sydney regarding somebody he saw before he was shot.

This was an exciting episode with some great surprises; it looks as if Sloane has shown his true colours and joined Elena although he is still claiming to be working for APO so perhaps he is just trying to get close to Elena so he can stop her plans. Although it was only one small scene I liked the interaction between Katya and Jack; Isabella Rossellini is great as Katya, it is a shame her character wasn't used more. The biggest surprise came in the final scene although I won't spoil it here!
