On TV this Halloween Wednesday: The X Factor goes live, 30 Rock refuses to leave its chad hanging, Supernatural revisits Benny and Dean’s purgatory stint, Face Off wraps its season and It’s the Great Pumpkin, Charlie Brown!

8 pm The X Factor (Fox) | Since the World Series ended so quickly, the Top 16 contestants will perform live tonight for the first time (treat!) — and new hosts Khloe Kardashian and Mario Lopez make their debut (trick?).

8 pm Survivor: Philippines (CBS) | The Tandang and Kalabaw tribes merge, and Lisa Whelchel is confronted about her past as a former TV teen star. Word to the wise? Do not mess with the Blair.

8 pm It’s the Great Pumpkin, Charlie Brown (ABC) | The animated special has been around since 1966, but maybe this will be the year that Linus finally sees the Great Pumpkin.

8 pm 30 Rock (NBC) | The last-ever Animal Practice was supposed to air here, but with the NBC’s Thursday comedy line-up pre-empted this week (by an encore of The Voice) the network is turning the slot over to a timely, election-themed ep of 30 Rock. (Watch preview.)

10 pm Nashville (ABC) | Two not-great developments for the future of Rayna and Teddy’s marriage: 1) She performs with Deacon at her hubby’s campaign fundraiser and 2) a woman from Teddy’s past (According to Jim‘s Kimberly Williams-Paisley, kicking off a multi-episode arc) shows up with a secret. Meanwhile, Juliette tries to polish her image via an interview with Good Morning America‘s Robin Roberts.

10 pm Chicago Fire (NBC) | Chief Boden is accused of leaving a homeless man to die in a warehouse fire, and things get uncomfortable when Shay runs into her ex-girlfriend Claire (Life Unexpected‘s Shiri Appleby) – and Claire’s husband – during a call.

10 pm Face Off (Syfy) | Season finale: Viewers choose the Season 3 winner. (Paint a smile on your face: The show’s been renewed for a fourth season.)

10 pm American Horror Story: Asylum (FX) | A violent storm cues up Movie Night at Briarcliff — as well as offers several inmates the perfect opportunity to escape. (The hour’s grisly final image, you will see, is pretty much inevitable.)
