As we settle into the fall TV season, two of our summer shows—The Knick and Manhattan—reach their seasons' end. Plus, C-3PO and R2-D2 return to TV, and a familiar DC villain pops up on The Flash. Get all the details below!
Gotham (8 PM, Fox)
It's not a good time to be a politician in Gotham City (although really, is it ever?). With the vote on the future of the Arkham district coming up, politicians on both sides of the vote are in danger and naturally, it's up to Gordon and Bullock to protect them.
The Originals (8 PM, The CW)
This week's episode flashes back to the 1700s, when things between Elijah and Marcel were friendlier. What a difference 300 years makes.
As tensions between Elijah (Daniel Gillies) and Hayley (Phoebe Tonkin) grow, Klaus (Joseph Morgan) steps in and encourages her to regain her position within her werewolf pack. Still under Davina's (Danielle Campbell) control, Mikael (Sebastian Roche) grows impatient while she attempts to uncover a spell that would protect those closest to her. When Elijah turns to Marcel (Charles Michael Davis) for help in tracking down a vital piece of information, he is forced to remember a time long ago when they were on better terms. Meanwhile, Davina and Kaleb (guest star Daniel Sharmon) find themselves in a dangerous situation when unexpected visitors show up and crash their dinner. Finally, Klaus grows suspicious after a meeting with Cassie (guest star Natalie Dreyfuss) doesn't go as he had planned.
Scorpion (9 PM, CBS)
This week, our team of geniuses is getting that requisite Vegas casino episode. Those tend to be over-the-top even in the best circumstances.
Sleepy Hollow (9 PM, Fox)

The Flash (8 PM, The CW)
Barry hasn't quite gotten the hang of his new powers and he passes out after foiling a group of robbers. But what's more intriguing is that it wasn't actually a group of robbers—it was Multiplex, a man who can create multiples of himself. In the meantime, Detective Green—ahem, I mean Joe—isn't overly pleased with Barry's vigilante activities.
Marvel's Agents of S.H.I.E.L.D. (9 PM, ABC)

Supernatural (9 PM, The CW)
Even Crowley thinks that demon Dean is becoming a bit too aggressive—which is saying something. Crowley believes that it's all part of the Mark of Cain, which needs to be fed.

Person of Interest (10 PM, CBS)
You know that thing where Reese is using the cover of an NYPD detective? Yeah, that's not working out so well with his latest case. He's protecting a brother and sister who become targets of a gang investigation.
Forever (10 PM, ABC)
When a junkie-turned community activist dies, it initially looks like a drug overdose, but ends up looking more and more like a murder involving a real estate developer and a wealthy community organizer. Naturally, this reminds Henry of his time as a physician in a tenement in the 1890s, because it wouldn't be Forever without a period flashback.
Also on tonight: new episodes of Face Off (9 PM, Syfy) and Town of the Living Dead (10 PM, Syfy).
Arrow (8 PM, The CW)
