'Agent Carter' Season 2 Recap: Zero Matter Takes Its Toll on Whitney Frost on Finale

Years after Captain America (supposedly) died, Hayley Atwell's Peggy Carter continued to be one of the best spies in the West, fighting to save the world behind the scenes during the Cold War. Read how, in the season two finale recap & spoilers of ABC's Agent Carter, the Marvel heroine finally managed to get rid of Zero Matter ... and Whitney Frost.

After trying to uncover the mysteries of  Zero Matter all entire season, Peggy's team, with help from billionaire-turned-film director Howard Stark (Dominic Cooper), finally managed to control this creepy substance. But it came at a price.

The season's last episode, "Hollywood Ending," begins with Dr. Jason Wilkes (Reggie Austin), unable to control himself any longer, appearing to explode with all the Zero Matter presence in his body. In the room are Vernon Masters (Kurtwood Smith) and season villain Whitney Frost (Wynn Everett).

By the beginning of the season finale, we find out that Jason and Whitney survived. The  Zero Matter has left his body and slid over to the movie star's body. When Peggy, Jack Thompson (Chad Michael Murray) and Daniel Sousa (Enver Gjokaj) are trying to escape her, Whitney's run over by a car; inside it are Edwin Jarvis (James D'Arcy) and Stark, here to save the day.

Whitney survives, of course, but the team has enough time to escape to Howard's mansion.

While Whitney loses her mind from all the Zero Matter in her body, her boyfriend, mobster Joseph Manfredi (Ken Marino), worries about how she's treating him and the fact that she doesn't eat, sleep or leave her room, obsessing over math problems to open the Zero Matter rift again. Concerned about the woman he loves, Manfredi makes a deal with the devil and goes to Stark's mansion. It turns out, of course, that the two are friends.

When Manfredi asks for their help, Howard hatches a plan that's not really a plan: They should just steal Whitney's calculations and build her idea, which is exactly what they do. 

Here, the geniuses unite: Jason, Howard and Aloysius Samberly (Matt Braunger) create a contraption that will open a portal to the Zero Matter dimension, creating a plan to have Whitney's power emptied and locked into the portal.

Echoing a line from '80s flick Field of Dreams, Jason says no one need tell Whitney they're opening a rift: If they build it, she will come -- and sure enough, she does.

They manage to deplete Whitney of her frightful powers, but as they try to close the rift, Howard's machine malfunctions. Now someone must approach the danger zone, where anything will get sucked into Zero Matter oblivion.

Sousa ties himself to the ground and approaches the lever to shut the thing down, but he ends up floating in the air. While Peggy, Thompson and Howard try to keep him down, Jarvis fetches Samberly and they throw one of Stark's cars into the rift, which explodes and shuts down: Zero Matter is in our world no more!

When we next see Whitney, she's at a mental institution, her face half-mangled. She's seeing her late husband, Calvin (Currie Graham). She attempts to scratch her face to regain her Zero Matter power.

After a job well done, Peggy's all set to go back to New York. She says goodbye to Howard and Jason in the mansion (they'll be working together now: Dr. Wilkes will now be in a Stark Industries project).

Jarvis' wife, Ana (Lotte Verbeek) returns from her stay at the hospital, and a guilt-ridden Peggy tries to apologize, but all's well between them.

Jarvis drives Peggy to the SSR offices, smoothly trying to persuade her to stay in Los Angeles instead of going to New York. A few minutes later, Peggy finds a to stay: She and Sousa finally kiss on his desk, and she's officially made her choice between her two suitors.

In the meantime, Jack, who hated his own time in L.A., is preparing to get back to his job in New York when someone knocks on his hotel room door and shoots him in the shoulder. It's unclear whether he'll survive this. The shooter, whose face is never seen, takes a few files from his portfolio.

Due to poor ratings, it's possible Agent Carter won't return for a season three, but there's always a chance ABC thinks this one through and we can see Peggy next year!

Or as Jarvis put it, one compelling reason to stay! #AgentCarter pic.twitter.com/MTeDU3raNd
