Monday June 16 11:30pm (PG) on Seven

On tonight’s episode of 30 ROCK, on the heels of Jack realising that GE head, Don Geiss may be retiring, Jack's nemesis, Devin, returns engaged to Don's daughter.

Always up for good competition, Jack shows up at a dinner where Devin and Don are and is invited to Don's house that weekend. However, when Kenneth accidentally lets it slip that Jack recently had a heart attack, Devin feels he can knock Jack out of the race.

Meanwhile, Liz tries to get her life in order after Jack and Jenna lay into her about getting it together; Jenna starts to enjoy the fame her fat is bringing her; and Kenneth plots to get Tracy and his wife back together.

RIP TORN AND WILL ARNETT GUEST STAR
