Ari and Andrew came up through the mailroom ranks together, but Klein ultimately succumbed to the pressure and went off to quietly build a solid TV agency in the safer confines of the Valley. When Andrew came to Ari looking for a loan, Ari re-launched him as the head of Miller-Gold's TV department. Too bad his success - and marriage -- came to an abrupt end when he began having an affair with his colleague Lizzie.
