Prelude

Summary

Jack takes drastic measures to ensure that the NSC never finds out the truth about Sydney's murder of a Russian diplomat.

Meanwhile, Sydney agrees to go on a mission with Sloane in order to thwart plans to obtain the operating system to a deadly weapon — and she discovers an unlikely ally in the hunt for her missing two years.
