THE RUNDOWN: Thursday, May 17

ABC
8:00 Missing #10 "Rain on the Evil and on the Good" (SERIES FINALE)
9:00 Grey's Anatomy #172 "Flight" (Season Finale)
10:00 Scandal #7 "Grant: For the People" (Season Finale)
ABC is all new on Thursday with finales across the board including the series finale of the cancelled Missing. I'd expect rises across the board for these shows.
Prediction: Missing - 7.0 million, 1.3/Grey's - 11.1 million, 3.8/Scandal - 7.1 million, 2.1

CBS
8:00 The Big Bang Theory #95 "The Isolation Permutation" (REPEAT)
8:30 Rules of Engagement #87 "Audrey's Shower" (Season Finale)
9:00 Person of Interest #23 "Firewall" (Season Finale)
10:00 The Mentalist #94 "The Crimson Hat" (Season Finale)
CBS is new from 8:30-11pm after a repeat of The Big Bang Theory, which already concluded its season. That could make things lower but they are season finales which often provide bumps. Therefore, I'd expect things to offset and I think we'll see similar numbers to last week.
Prediction: Rules - 7.9 million, 2.6/Person - 13.4 million, 2.6/Mentalist - 13.1 million, 2.5

NBC
8:00 Community #69 "Digital Estate Planning"
8:30 30 Rock #125 "What Will Happen to the Gang Next Year?" (Season Finale)
9:000 Community #70 "The First Chang Dynasty"
9:30 Community #71 "Introduction to Finality" (Season Finale) 
10:00 Awake #12 "Two Birds"
NBC is all new with three episodes of Community including the season finale plus the season finale of 30 Rock. Given that these two shows are so niche, I would expect a very very low night for NBC.
Prediction: Community 8:00 - 3.0 million, 1.3/30 Rock - 3.2 million, 1.5/Community 9:00 - 3.3 million, 1.4/Community 9:30 - 3.6 million, 1.5/Awake - 2.4 million, 0.7

FOX
8:00 American Idol
9:00 Touch #10 "Tesellations"
FOX is all new with its regular lineup. Against finales on ABC and CBS, I could see numbers being down this week.
Prediction: Idol - 15.1 million, 3.9/Touch - 6.4 million, 1.8
