A quarantine haircut may be responsible for a “Billions” plot twist.

Katie Nolan joked on Twitter with the show’s creator, Brian Koppelman, that the program may want to consider a new direction for the Mafee character, played by Nolan’s boyfriend, Dan Soder.

“Hey totally random but what if mafee spent the second half of the season getting really into hats?” Nolan tweeted, followed by a photo of hair on the floor.

“All different types of hats. A lot of people are talking about what a great arc this would be for the character and I gotta say I agree!”

The first seven episodes of Season 5 of “Billions” is currently airing. Showtime had to pause production of the show due to the coronavirus pandemic.

Page Six was the first to report Nolan and Soder are dating.
