When Sydney is looking at her name on the CIA's wall of the deceased the name that appears right below hers is Scott Chambliss, the show's production designer.
There are over 15 names of "Alias" crew members from various departments listed on the "Agents Killed in Action" memorial plaque that Sidney and Jack view at 12:41. Most obvious is Scott Chambliss, production designer, whose name appears under Sydney's in a closeup.
Prior to this episode, Jack had been in solitary confinement for almost a year, yet he knows more about current operations than Dixon.
