What to watch on Monday, May 13...
8:30pm, Cartoon Network
Jake and Finn spend “Shh!” communicating via signs, in what may be an homage to either “Hush” or Wile E. Coyote. Then in “Card Quest,” the guys match wits in the titular fantasy card game.
SERIES FINALE, 8pm, The CW
“We All Fall Down” concludes the series with a devastating incident that unites the gang and reminds them of their bonds. That incident may or may not be linked to the episode's featured performance by Goo Goo Dolls, and/or the apparent time vortex that sucked everyone back to 1999, when Goo Goo Dolls performing on national television might be a thing. But first, the cast and crew share a retrospective of the show’s “many unforgettable moments.” I won’t bother to list any examples because you all surely remember them so well.
SEASON 8 FINALE, 8pm, CBS
How I Met Your Mother
With their knot-tying just around the corner, Robin and Barney pause to decompress for a night—or they would, but for the irritating intrusions of Casey Wilson and Keegan-Michael Key. Elsewhere in “Something New,” Marshall and baby Marvin visit St. Cloud, and Lily checks out Ted’s progress turning his fixer-upper home into another grand metaphor for fate or romance or who the hell even knows anymore.
SEASON 2 FINALE, 9pm, CBS
2 Broke Girls
The expansive mythology of the 2 Broke Girlsverse deepens further in “And the Window of Opportunity,” as Max and Caroline explore a long-hidden section of the diner while cleaning. There, they unearth something that could rejuvenate their cupcake business. Probably a big glowing hole with a cork in it, right? Probably.
A prisoner transport out of town leads Nolan and Amanda into peril in “The Serpent’s Egg,” though the show’s recently announced Season 2 renewal suggests they’ll pull through. Back in town, Irisa encounters a man she believes traumatized her as a child.
“The Big Snag” hurls Pete and Myka into a world of hardboiled hoods and femme fatales when their latest artifact hunt takes place inside a film noir universe. In the technicolor world, Artie, Steve, and Claudia pursue a phantom car thief.
SEASON 5 FINALE, 10pm, ABC
Beckett takes stock of her career—and her relationship with Castle—after she interviews for a position with the feds in “Watershed.” At her current job, she and the team look into the death of a woman found bobbing in a water tank in dilapidated digs.
Y’know, in my day, a double date meant taking in a drive-in movie and then maybe zipping over to the local malt shoppe for a couple of ice cream sodas. But for Miles and Nora and for Charlie and Jason, apparently romance blossoms while fleeing from devastating drone strikes launched by an enemy militia. Kids these days! In the less heated events of “The Longest Day,” an assassination attempt drives Monroe even buggier, while Rachel and Aaron enter Colorado, where they can finally unwind properly, if you know what I mean.
Daniel’s grasp on reality starts to slip in “Drip, Drip” as he continues to experience difficulty adapting to life on the outside. This sounds like a job for the tiny green space alien only Daniel can see. Meanwhile, Ted Jr. raises questions about the man’s alleged innocence.
