A stolen piece of art is the key for locating a weapon's dealer. Chuck's up for a promotion to assistant manager at work.
Now deprogramming Chuck is off, he gets a first, apparently easy mission, locating stolen art.

Meanwhile Casey and Sarah still deeply distrust each-other, each taking a cover job at Buy More and wriggling in at Bartowski home events.—KGF Vissers
