Today:

Adventure Time (7:30 PM, Cartoon Network)

This time around, we're going ultra low key again, with apparently no big guest stars or massive quests: "“Shh!” — Finn and Jake hold a contest to see who can last longer without talking." That's followed by Regular Show and Mad.

Defiance (9 PM, Syfy):

This show has already gotten renewed for a second season — but producer Michael Taylor (Battlestar Galactica, Star Trek: Deep Space Nine, Virtuality) won't be along for the ride. Which is too bad, since Taylor's probably one of the main ingredients keeping the show quirky and weird, instead of just formulaic. So what's up this week? "While Irisa faces a threat from her past, while Nolan and Amanda lead an expedition outside of Defiance."

Warehouse 13 (10 PM, Syfy):

Enrico Colantoni, aka Keith Mars and Elias, guest-stars in a special noir installment! In which: "Pete and Myka get sucked into a 1940s detective noir novel in search of an artifact. Meanwhile, Artie, Steve, and Claudia chase down a phantom car thief."

Going Ape (10 PM, National Geographic):

A brand new show about primates, to get you up to speed before the new Planet of the Apes movie.

Do apes and humans have the same way of flirting and trying to hook up? Do men meeting for the first time look classically like chimpanzees establishing dominance? And do children sneaking candy parallel chimps deceiving their alpha male? Six million years ago, we branched off from the family tree we share with our ape cousins and monkey uncles. We may have evolved since then, but there's still an ape in all of us.... Going Ape, premiering on Monday, May 13, at 10 p.m. ET/PT on the National Geographic Channel (NGC), following the new hit series Brain Games, looks to our primate predecessors to understand human interaction and social dynamics. Not only do humans share 98 percent of our genetic code with our closest ape relatives, we also share some of the same inherent basic instincts. This revealing, often comic three-part series explores humans' daily battles for power, territory, sex and allegiance with that of our monkey cousins through humorous experiments, hidden camera footage, wildlife footage and expert analysis.

Revolution (10 PM, NBC):

There's nothing like watching your childhood sweetheart get gunned down in front of you to put you in the mood for romance.

AS ACTION HEIGHTENS, SO DOES ROMANCE AMONG THE CORE REBELS-Romantic connections heat up between two couples — Miles (Billy Burke) and Nora (Daniella Alonso) and Charlie (Tracy Spiridakos) and Jason (JD Pardo) — but disastrous drone strikes from the Militia threaten them all. An assassination attempt on Monroe (David Lyons) heightens his paranoia and Georgia Federation President Foster (guest star Leslie Hope) contemplates surrender. Meanwhile, Rachel (Elizabeth Mitchell) and Aaron (Zak Orth) push through the Plains Nation into Colorado.

Also on TV tonight: There's a new Brain Games on National Geographic at 9:30 PM. At 10 PM, there's the season finale of Castle on ABC.


Tuesday:

Johnny Test (7:00 PM, Cartoon Network):

Remember this show about a kid whose sisters test weird science on him? This time around, he's fighting someone named Dark Vegan! Here's what to expect: "“Johnny’s #1 Fan” — Johnny and Dark Vegan face off again, but this time Johnny has a Number 1 Fan on his side." There's also a new Teen Titans Go! and a new Looney Tunes Show.

Grimm (10 PM, NBC):

Continuing this show's recent trend of branching out beyond fairytale monsters, this time we're having zombies!

ZOMBIES DESCEND ON PORTLAND - JAMES FRAIN AND SHOHREH AGHDASHLOO GUEST STAR —Nick (David Giuntoli) and Hank (Russell Hornsby) discover a new kind of strange when they investigate suspects being found dead - for the second time. In Europe, Adalind (Claire Coffee) finds herself in the middle of a feud between Frau Pech and Stefania (guest star Shohreh Aghdashloo ) while working over the details of her pending transaction. Meanwhile, determined to remember every last detail to get things started once more, Juliette (Bitsie Tulloch) insists Monroe (Silas Weir Mitchell) share with her Nick's darkest secret - the world of Grimms and Wesen.


Wednesday:

Arrow (8 PM, The CW):

It's the season finale! Are you as jazzed as we are to see the final (?) John Barrowman/Steven Amell confrontation?

HEROES ARE FORGED AND SACRIFICES MADE IN THIS EPIC SEASON FINALE — Oliver (Stephen Amell) and Diggle (David Ramsey) race to stop the Dark Archer (John Barrowman) from unleashing his vengeance on The Glades. However, they run into a roadblock after Detective Lance (Paul Blackthorne) picks up Felicity for questioning. Tommy (Colin Donnell) and Oliver’s already tumultuous relationship takes a turn for the worse after Oliver makes a confession about Laurel (Katie Cassidy). After hearing of the danger in The Glades, Thea (Willa Holland) races to find Roy (Colton Haynes), inadvertently putting herself directly in the line of fire for Malcolm’s (John Barrowman) devious plan. On the island, Oliver, Slade (Manu Bennett) and Shado (guest star Celina Jade) are locked in a life-or-death struggle against Fyers (guest star Sebastian Dunn) as his missiles lock on a full Ferris Air jetliner.

Supernatural (9 PM, The CW):

This show, too, is having a season finale. Will they actually seal Hell? That would be kind of a fascinating game-changer. Let's hope this episode doesn't pull its punches:

WHAT MUST SAM, DEAN AND CASTIEL SACRIFICE TO FOREVER SEAL HELL? — With Crowley (guest star Mark Sheppard) poised to undo all the good they’ve ever done as hunters, Sam (Jared Padalecki) and Dean (Jensen Ackles) find themselves cornered.

Metatron (guest star Curtis Armstrong) initiates a plan with Castiel (Misha Collins) to take on Naomi (guest star Amanda Tapping) and the bureaucracy of Heaven.

Star Trek: Secrets of the Universe (10 PM, History):

Do you need yet another Star Trek documentary? Maybe, if it includes David Brin. According to Brin, this show is "A fun romp through the range of speculative sci & tech that serve as foundations and help propel the fabulous Trek franchise to realms of vast imagining and hopeful possibility."

Also on TV tonight: There's more Nature, about the "great zebra exodus," on PBS at 8 PM. At 9 PM, there's a new Mythbusters on Discovery. Syfy has the season finale of Deep South Paranormal at 10 PM, plus USA has a new Psych and PBS has Secrets of the Dead, focusing on a mysterious dead caveman.

The team races to find a way to stop Amanda, but with a diminished Division, they might finally be out-gunned.

Da Vinci's Demons (9 PM, Starz):

Now that Da Vinci has used bestiality to get out of those sodomy charges, what's next on his agenda? Meeting Dracula! No, we're not kidding.

The Turk's clue about the Book of Leaves leads Leonardo to Wallachia and an encounter with Vlad Dracula, while Lorenzo and Piero have a meeting with the Duke of Urbino. Later, the spy search intensifies.

Saturday:

Doctor Who (8 PM, BBC America):

So here it is — the culmination of Steven Moffat's master plan. We find out why the TARDIS blew up in season five, and why the Doctor's companion's daughter was kidnapped as a baby and brainwashed to become an assassin astronaut and then his wife. The whole deal — we're learning the Doctor's name, and presumably why it was such an important piece of information. Here's the official synopsis:

In "The Name of the Doctor," Clara (JENNA-LOUISE COLEMAN) is summoned to an impossible conference call, alerting her that the deadly Whisper Men are closing in on Vastra, Jenny and Strax. Someone is kidnapping the Doctor (MATT SMITH)'s friends, leading him toward the one place in all of time and space that he should never go. It's a deadly trap that threatens to unravel his past, present and future...

Orphan Black (9 PM, BBC America):

This show, too, has been renewed for another season, and meanwhile the clone-on-clone action is ramping up!

“You wanna mess with my life, I’m gonna mess with yours.”
“It’s time I told you what’s really going on.”

Sarah’s actions pit the Orphans against each other as she tries to plan her next move. As Paul tries desperately to cover up Sarah’s existence, Alison takes vengeance on her suspected monitor, which could cost her everything she holds dear.

What — did you think we meant some other wedding? Actually, after all the build-up, looks like Tyrion and Sansa are finally going to tie the knot. And maybe they'll form a bulwark of mutual support and kindness, in the midst of all this backstabbing? (Ha. I kid.)

King's Landing hosts a wedding, and Tyrion and Sansa spend the night together. Daenerys meets the Titan's Bastard. Davos (Liam Cunningham) demands proof from Melisandre. Sam (John Bradley) and Gilly (Hannah Murray) meet an older gentleman.
