Interview: London Brown Breaks Down Marvin's Final Journey in Power Book III: Raising Kanan Season 5

As Power Book III: Raising Kanan prepares to close out its story, fans are getting ready to say goodbye to one of the franchise's most beloved characters: Marvin Thomas. Over the course of four seasons, Marvin has evolved from the family's unpredictable enforcer into one of the show's most layered and emotionally complex characters. Now, heading into the final season, actor London Brown says Marvin's priorities have become clearer than ever.

Speaking with The TV Cave ahead of the Season 5 premiere, Brown reflected on Marvin's loyalty, his grief, and why audiences have connected so deeply with the character's growth. "I'm excited for the audience to see the work that we've been putting in," Brown said of the show's final chapter. "I've been asking for it. So I'm like, cool, finally it's here." One of the biggest questions entering the season is where Marvin's loyalty ultimately lies. Throughout the series, he's been fiercely protective of his sister Raquel and his nephew Kanan, but Brown believes Marvin's focus has shifted.

"I probably would put it with his daughter first," Brown explained. "He's lost control over his nephew. His nephew's not listening anymore. So because of that, Marvin's like, all right, let me try to at least cover my daughter while I can." That protective instinct has always defined Marvin, but it becomes even more significant as he continues to process the devastating losses that have reshaped the Thomas family.

Brown also spoke about Marvin's relationship with his younger brother Lulu, played by Malcolm Mays. According to the actor, Marvin's role as the oldest sibling has always fueled his desire to protect those around him.

"There's always this need to protect, look after, and cover," Brown said. "Once Marvin realizes that he was unable to do that, that sets him off.

As the season unfolds, Marvin finds himself emotionally overwhelmed, trying to balance his responsibility to his daughter while also coping with the fractured state of his family. "There's a part of Marvin that feels like he's drowning emotionally," Brown shared.

The emotional side of Marvin is one reason Brown believes fans have embraced the character over the years. While viewers appreciate Marvin's willingness to handle business when necessary, they also connect with his vulnerability as a father.

"Dealing with his daughter shows the vulnerability that the audience can connect to," Brown said. "That's outside of guns. It's just him being the dad and trying to figure it out." Of course, Brown acknowledged that Marvin's appeal goes beyond his family relationships.

"The streets really arrive with Marvin with that," he said, referring to the character's reputation as someone who gets things done when situations become dangerous. When asked whether Marvin is misunderstood, Brown argued that viewers may have initially judged the character too harshly during the show's early seasons.

"I think people think he's a little more irresponsible than what I think he actually is," Brown explained. "His intentions are good. He's not trying to mess up things." According to Brown, fans have gradually come to realize that Marvin is often the most dependable person in the room when the pressure is at its highest.

"If you had to go handle some business, I feel like most of the audience is like, 'I'm calling Marvin,'" Brown joked. That's probably one of the biggest compliments a Power character can receive. As Raising Kanan enters its final season, Marvin's evolution remains one of the series' greatest success stories. He's still capable of delivering intimidation when necessary, but his emotional growth, dedication to family, and willingness to confront his flaws have transformed him into a fan favorite. If Brown's comments are any indication, Marvin's final ride may also be his most emotional one yet.
