leslie knope london parks and recreation 'Parks and Recreation,' 'Glee' and more Thursday night premieresThursday, Sept. 26 is a big night during premiere week — there are seven returning shows, two new premieres, the “X Factor” Top 40 and a partridge in a pear tree. Here’s what to look forward to:

ABC has a two-hour return of “Grey’s Anatomy” that teases a mudslide, infidelity and a possible death. It is preceded by a rerun of “Marvel’s Agents of SHIELD” premiere episode, in case you missed that the first time around.

On CBS, “The Big Bang Theory” is back with Sheldon and Penny bonding time (which might be our favorite two-person combination on “TBBT”), followed by Robin Williams‘ return to TV on “The Crazy Ones” and Amber Tamblyn‘s return to TV on “Two and a Half Men” as Charlie Sheen‘s character’s long-lost daughter.

Then “Elementary” whisks us off to London where Sherlock and Watson encounter Sherlock’s older brother, Mycroft (Rhys Ifans).

Speaking of London, on NBC, the “Parks and Recreation” crew is heading across the pond, when Leslie has to accept an award in merry old England, while Ann and Chris take the next step (the next step to being off the show).

“Parks and Rec” is followed by Michael J. Fox’s return to TV with a self-titled show where he plays a retired newsman with Parkinson’s who decides to go back to work; and then the “Parenthood” premiere, which promises some lighter fare for the Braverman clan.

Not to be left out, FOX is revealing the Top 40 contestants on “The X Factor,” followed by “Glee’s” Beatles episode, which sees Kurt and Blaine re-evaluating their relationship.

Which shows are you most looking forward to?
