Comedian Patton Oswalt returned to Marvel’s Agents of S.H.I.E.L.D. this week, playing three of the four Koenig brothers (RIP Eric) in “Hot Potato Soup.” A lot has changed since the Koenigs were last seen in the Marvel Universe, such as Daisy/Skye evolving into the superhero Quake (Chloe Bennet). Sam Koenig, a passionate uber-nerd, constantly gushes over his proximity to Quake, even though they’ve known each other for a long time. This week, Sam brought up how much the superhero fans in the MCU admire Quake, and he lets it slip that he’s read fan fiction about Quake and Black Widow.

In fact, he says there’s “a library of fanfiction” on the internet about her. “You should Google it,” he tells her, before clearing his throat. “Actually, no, you shouldn’t. You shouldn’t. Forget I said that. Some of it … little on the steamier side.” Sam adds, unconvincingly, that he hasn’t read any of the fan rumblings, but he clarifies: “I mean, they got you shipping with Black Widow!”

Sam’s right: The internet loves a potential romance between Quake and Natasha Romanoff, the Russian super spy played by Scarlett Johansson in the Avengers films. Though Quake/Widow isn’t the most popular ship among Marvel fans — that honor goes to “Stucky” for Steve Rogers and his best bud Bucky — “steamy” doesn’t even begin to describe such literature like The Quaking Widow by ironArcher8656. In it, Skye and Natasha team up with the author to infiltrate a gentlemen’s club and they get pretty close while on the job.

Because of the very real and very ugly distance between Marvel Studios and Marvel Television, it’s unlikely that The Quaking Widow or virtually any sort of crossover will occur on camera. But it’s fun to know that even writers within the Marvel Universe are aware of “Quack”.

Marvel’s Agents of S.H.I.E.L.D. airs Tuesdays on ABC.
