‘A Million Little Things’ Season 4 Cast: Are the Newcomers All Here to Stay?

When viewers watched A Million Little Things Season 4 Episode 2, “Not the Plan,” numerous questions arose about the cast. Michael Patrick Thorton, Mark Derwin, Rachel Nichols, and Nikiva Dionne joined the cast of A Million Little Things Season 4. With Delilah Dixon (Stephanie Szostak) and Danny Dixon (Chance Hurstfield) leaving for France, it makes sense for the writers to bring in a few new characters. However, viewers want to know why they all look so familiar and if the newbies are here to stay.

Who plays Nick in the ‘A Million Little Things’ Season 4 cast?

In A Million Little Things Season 4, Maggie Bloom (Allison Miller) takes on a new temporary position for the fired Dr. Stacy. She’s very excited to counsel patients who call in to a radio show for help. However, the traffic and weather guru gives her a hard time before she even gets her morning cup of coffee. Mark Derwin portrays Nick, and he’s determined to make things difficult for Maggie. After he prank calls Maggie while on air, she cancels his traffic and weather report. In her defense, she’s helping a young child who worries about her mom’s drinking and driving. However, Nick explains to Maggie that his job is essential, too.

In the next episode of A Million Little Things, the ABC synopsis reads, “Maggie is blindsided by some news.” Then in the following episode, “Pinocchio,” Maggie deals with politics at work. Since Maggie’s storyline revolves around her radio show position this season, it’s safe to say that viewers will see Nick return to the A Million Little Things Season 4 cast. Viewers might recognize Derwin from any number of his Soap Opera roles, including Guiding Light and Days of our Lives. He also starred as George Juergens on the ABC Family TV show The Secret Life of the American Teenager from 2008 to 2013.

Michael Patrick Thorton plays Eddie’s new therapist, Russ

In A Million Little Things Season 4 Episode 2, Darcy Cooper (Floriana Lima) introduced Eddie Saville (David Giuntoli) to his new therapist, Russ (Michael Patrick Thorton). Luckily, the two men hit it off, and Russ pushes Eddie to stop living in the past. Thornton is in the upcoming promos for the ABC series, so he is another recurring character this season.

ABC viewers might recognize Thorton for his recurring role as Dr. Gabriel Fife in the Grey’s Anatomy spinoff series Private Practice.

Nikiva Dionne returns to the ‘A Million Little Things’ Season 4 cast as Shanice Williamson

Nikiva Dionne is not a brand new character added to the A Million Little Things Season 4 cast. Viewers remember Shanice Williamson from season 3 when she took the role of Regina in Rome’s movie. However, the coronavirus (COVID-19) pandemic took everyone by surprise, and the network shut down the production of Rome’s film. Shanice returned with her daughter and became friends with Katherine (Grace Park) in season 4. Dionne becomes another recurring character this season, joining the women for a celebratory party after Katherine’s divorce. Viewers might recognize Dionne as Stacy Sutton in HBO’s Insecure or Deputy DA Nia Wells in CBS’s S.W.A.T.

Rachel Nichols as the ‘Blonde woman’

The last newcomer to the A Million Little Things Season 4 cast on Sept. 29 was Rachel Nichols. She appeared briefly at the very end of the episode, and viewers thought she might be the one responsible for Eddie’s hit-and-run accident. In episode 3 of the season, Eddie sits down at a restaurant with Nichols; however, the press image doesn’t indicate who she plays. According to the press release about episode 3, she might be someone from Eddie’s past. Whoever she is, Nichols plays a recurring role in A Million Little Things Season 4, credited as “Blonde Woman” for now.

Viewers often confuse Nichols with the sports analyst Rachel Nichols, so in 2021, she changed her Twitter user name to “Actress, Not ESPN.” Fans might recognize the non-sportscaster from her roles in Criminal MindsConan the Barbarian, or Continuum

According to IMDbA Million Little Things Season 4 airs Wednesdays at 10 p.m. EST on ABC and is available for streaming the next day on Hulu.
