Alias

Sloane said that 3 CIA analysts were killed when the Index was stolen, but the written briefing Dixon has when he meets Sydney in secret indicates that 4 agents were killed.

Goof: Chase tells Dixon that Sloane is authorized to contact his former associates. In the previous two episodes he had to step down as APO Director because the situation involved former associates. One would assume that if Sloane were unable to contact any of his former associates he would be pretty useless at his job. In the previous episodes it was stated that Sloane could not have contact with a select number of his former associates who were on a list, including Anna Espinosa and Sark. It seems that the man he contacted in this episode is not on that list.

Number 47: When Dixon runs a backtrace on one of Sloane's calls it shows the address "Avdage Stepe 47".

Number 47: Sloane's vehicle ID shown in the satellite tracker is 30947 28436.

The dinner scene in Sloane's house is very similar to the one in season one's "Page 47."

Wouldn't director Chase be a bit too high in the CIA's hierarchy to risk being killed or even captured in a regular raid?

The show revisits the false TV cliche that something can be put in a coin operated locker and will stay there indefinately until someone with a key collects it. In truth these lockers are emptied regularly and if an item is left inside it is stored and the locker rekeyed, otherwise the operator would suffer financial loss, While as the story turns out in this case the envelope could have been placed in the locker in the last 24 hours, why did Vaughn just accept that the package was still in the locker when he got to it, if he thought his uncle placed it there?

Goof: Sydney welds through a metal grate and touches the metal immediately. Unless that was some sort of special CIA cool welder she should have been burned by the hot metal.

Goof: Near the end, Nadia crashes through the garage door of building 37 in the red Mustang. A few minutes later, the car is seen without a scratch.

When the overview of Brussels is shown, there are mountains in the background. In Belgium there aren't any mountains as high as those shown, and certainly not around Brussels. Also, the map indicating the "port area" isn't Brussels. Another detail: when you need a "fast car" in Europe, one wouldn't import an American Muscle Car for the occasion, but use what's at hand. So the Mustang isn't exactly in place. They did get the plates right, though. However, all the Belgian cars use the same plate. Also, there is no Rue Voltaire in Brussels. There is only an Avenue Voltaire which is indeed close to the dockside.
