Marvel Agents of SHIELD will be welcoming back Cobie Smulders as Maria Hill this week, prompting fans of the show to wonder if Smulders might become a regular on the series in the future.

Cobie Smulders On 'SHIELD'

On Friday, ABC released a sneak peak of this week’s episode of SHIELD, "Nothing Personal," in which Maria Hill is featured. In the short clip, Coulson and some of his team are hiding out when they’re found by Colonel Talbot. Coulson eventually learns that it was Hill who leaked his location to Talbot.

Smulders can currently be seen playing Maria Hill on the big screen in Captain America: The Winter Soldier. In the film, HYDRA causes the demise of SHIELD, forcing Hill to seek employment with Stark Industries. The development in the movie could spell a need for the TV series to figure out how to bring SHIELD back or how everyone will adapt without unit.

In any case, Smulders' guest-starring appearance could mean that she’s considering coming onboard the series full-time. The producers are reportedly making a big effort to get Smulders to sign on as a series regular for season two of SHIELD, according to TV Guide.

Since Smulders' nine year run on CBS sitcom How I Met Your Mother came to an end earlier this year with the series’ finale, she could potentially have the availability for the Marvel series. However, Smulders is thought to be focusing on her film career and is currently filming Avengers: Age of Ultron.

Marvel Agents of SHIELD airs Tuesdays on ABC at 9/8c.
