Succession is the second episode of Season 3 of Alias and the 46th episode overall. Sydney's search for her past leads to a jailed Sark, but their Q&A is cut short when he becomes the ransom for a pair of abducted CIA scientists, whose kidnappers may be tied to the murder of his father. Jack Bristow contacts an old friend of sorts for info on Arvin Sloane's new world-peace project, and Michael Vaughn makes a decision about his future as an operative.
