After a long wait, CBS has announced the return of Person of Interest: Tuesday, May 3 at 10pm. Now, that doesn't mean they're airing it only once a week; starting the week after, it will air BOTH Monday at 10 and Tuesday at 10 until its finale on June 21.
Speaking of airing twice a week, starting that same week The Odd Couple will start to air Monday at 9:30 in addition to Thursday at 8:30 starting the week of May 2.
On April 25, CBS will double-pump the remainder of Mike & Molly episodes Mondays in the 8pm hour.
UPDATE: For anyone who was in doubt, Person of Interest will officially end this season.
