It is Mission Accomplished for The Big Bang Theory on Monday. The blockbuster comedy was tasked with launching similarly themed new drama Scorpion this fall, and it did. After being nurtured for four weeks with back-to-back episodes of Big Bang Theory in front of it, Scorpion got its first test last night, the last with Big Bang in the CBS Monday lineup before the comedy returns to Thursday. With its new lead-in, The Millers (2.2), at 8:30 PM vs. a Big Bang rerun last week (2.9 in the fast nationals), Scorpion (2.4, even) held steady, an encouraging sign that the show has developed a loyal following. A Back 9 order for the action hour, once again the most watched Monday drama (10.5 million), is a lock.

Back to The Millers (2.2), which opened its second season on a new night with its old lead-in, Big Bang Theory (4.4, down a tenth from last week but may be adjusted up in the finals). Millers was down 33% from its series premiere on Thursday last fall when it held onto 66% of its Big Bang lead-in versus an unimpressive 50% last night. The Millers was on par with its season finale (2.9, 50% Big Bang lead-in retention). For the sophomore comedy, which has aired behind Big Bang since the start, the real test will come next week when it will follow a different show for the first time, 2 Broke Girls. Still, the family comedy is far from doomed. After a fall run on Monday, it is poised to return to its cushy post-Big Bang berth on Thursdays. Finally, an uptick for NCIS: Los Angeles (1.7, +6%), which has been fading in its new Monday slot. With Castle dropping to a 1.6, the NCIS spinoff rose to its first No. 2 finish in the 10 PM hour.

For a second straight time, the CW’s fast nationals were skewed by a local NFL preemption. Last week, there were no significant downward adjustments for both Jane and The Originals (0.7 last night, even with last week). This time the affected market is larger — No. 10 Houston vs. No. 21 St. Louis last Monday — so the impact could be bigger, but even if it’s adjusted down a tenth, Jane would still be on par with its debut, which is a good sign. Expect full-season orders from the CW for Jane and breakout The Flash soon.

After a strong start for the battle rounds last week, NBC’s The Voice (3.3) was  down -18% week-to-week. The Blacklist (2.4) followed suit, down -14%. The network still topped Monday in 18-49 (3.0) and total viewers (10.9 million).

Fox’s sophomore Sleepy Hollow (1.7) is starting to catch up with hot newcomer Gotham (2.2). Sleepy Hollow inched up a tenth, while Gotham slipped -8%.

ABC also is dealing with possible fast national ratings inflation due to a local NFL preemption. For the moment, Dancing With The Stars (2.0) is up a tenth from its fast national last Monday, while Castle (1.6) is down -16% from last week to tie its series low in Live+Same Day.
