Which Blue Bloods Characters Should Cameo in Boston Blue?

Introduction

The Blue Bloods universe is getting a fresh chapter with Boston Blue, a spinoff premiering on CBS on October 17, 2025, at 10/9c. Fans of the original series, which wrapped its 14-season run in December 2024, are buzzing about who from the Reagan family might pop up in this new show centered on Donnie Wahlberg’s Danny Reagan. Boston Blue follows Danny as he trades New York’s gritty streets for Boston’s, partnering with Detective Lena Silver (Sonequa Martin-Green) in a new city with its own law enforcement family. Why does this matter? For fans, it’s about keeping the Reagan legacy alive—those Sunday family dinners, the moral dilemmas, the cop life. The excitement is real, especially after Wahlberg teased “mind-blowing” surprises in the premiere. A TV Insider poll from August 2025 asked fans which Blue Bloods characters they’re dying to see cameo in Boston Blue. Let’s break down the top contenders, why they’d fit, and what could go wrong if the spinoff doesn’t deliver.

Why Cameos Matter in Boston Blue

Cameos in Boston Blue aren’t just fan service; they’re a bridge between the old and new. Blue Bloods thrived on the Reagan family’s tight-knit dynamic—Frank’s stoic leadership, Danny’s hotheaded justice, Erin’s legal battles. Bringing back familiar faces keeps that emotional core intact while introducing Boston’s Silver family. The risk? Overloading with cameos could overshadow new characters like Lena Silver or Mae Silver (Gloria Reuben). Fans want connection, not a rehash.

• Emotional Stakes: Cameos remind viewers of Danny’s roots. For example, Erin Reagan’s confirmed guest spot in the premiere ties Danny’s Boston move to his New York past. Without these, the show might feel like a generic cop drama.
• How It’s Done: Showrunners Brandon Sonnier and Margolis must balance old and new. Bridget Moynahan’s Erin cameo, announced in July 2025, sets the tone—brief but meaningful.
• Common Mistakes: Too many cameos can dilute the plot. Blue Bloods spinoffs like Boston Blue risk alienating new viewers if they lean too hard on nostalgia.
• Consequences of Errors: If cameos feel forced, fans might tune out. A misstep could make Boston Blue seem like a cash grab rather than a worthy “universe expansion.”

Erin Reagan: The Confirmed Cameo

Bridget Moynahan is already set to reprise her role as Erin Reagan in the Boston Blue premiere, a move that’s got fans hyped. Erin, the Assistant District Attorney in New York, brings a legal perspective that could clash or align with Boston’s DA, Mae Silver. Wahlberg teased this reunion on Instagram in July 2025, calling Moynahan his “TV sister.”

• Why It Matters: Erin’s presence grounds Danny’s story. As his sister, she’s a link to the Reagan family’s moral code, especially after Blue Bloods ended with Erin proposing to retry her marriage with Jack Boyle.
• How It’s Done: Erin’s cameo is likely a one-episode deal, possibly involving a case that crosses state lines. Moynahan’s also directing, adding her creative stamp.
• Common Mistakes: Fans might expect Erin to stick around, but overusing her could sideline Lena Silver’s arc. The show needs to focus on Boston’s new dynamics.
• Consequences of Errors: If Erin’s cameo feels like a stunt, it could frustrate viewers who want Boston Blue to stand on its own. Fans on X have already voiced this concern, fearing a “Reagan overload.”

Maria Baez: The Romantic Hope

Maria Baez (Marisa Ramirez), Danny’s NYPD partner, is a top fan pick for a cameo, fueled by their romantic tease in the Blue Bloods finale. Wahlberg’s winking emoji response to a fan’s Instagram comment about Baez has kept hope alive.

• Why It Matters: The finale’s pizza date hinted at a future for Danny and Maria. Fans want closure, especially since Danny’s a widower after Linda’s 2017 death. A cameo could explore this spark in Boston.
• How It’s Done: Baez could visit Danny for a personal or professional reason—maybe a joint NYPD-Boston PD case. Her chemistry with Danny would add emotional depth.
• Common Mistakes: Ignoring Baez could alienate fans who invested in their slow-burn romance. Conversely, forcing a love story might feel contrived if it doesn’t fit the plot.
• Consequences of Errors: If Baez doesn’t appear, fans might feel cheated, as seen in X posts demanding her return. A poorly handled cameo could also disrupt Danny’s new life in Boston.

Jamie and Eddie: The Family Tie

Jamie Reagan (Will Estes) and Eddie Janko (Vanessa Ray), Danny’s brother and sister-in-law, are fan favorites for a Boston Blue cameo. Wahlberg’s Instagram replies, like “He’d better come visit his big brother,” fuel speculation. Vanessa Ray told TV Insider in October 2024 she’d jump at the chance, even joking about playing a new character.

• Why It Matters: Jamie and Eddie’s new parenthood (revealed in the Blue Bloods finale) makes them relatable. Their visit could show Danny as a supportive brother, reinforcing family themes.
• How It’s Done: A family trip to Boston, perhaps with their baby, could work. It’d be a chance to see Jamie’s growth from rookie to sergeant alongside Danny’s new role.
• Common Mistakes: A cameo without purpose—like a random visit—could feel hollow. The show must avoid making Jamie and Eddie mere props.
• Consequences of Errors: Fans might lose trust if the cameo lacks depth, especially since X posts show excitement for a “Reagan family reunion.” A weak appearance could hurt the show’s momentum.

Sean and Jack Reagan: Danny’s Sons

Danny’s sons, Sean (now played by Mika Amonsen) and Jack (Tony Terraciano), are strong contenders. Sean’s confirmed as a series regular in Boston Blue, starting his career as a Boston PD patrolman. Jack’s return is less certain but desired, as Wahlberg teased both sons on Instagram.

• Why It Matters: Danny’s move to Boston is partly to reconnect with Sean, who’s forging his own path. Jack, being older, could tie up loose ends from Blue Bloods. Their presence keeps Danny’s fatherhood central.
• How It’s Done: Sean’s role as a regular means he’ll interact with Danny often, likely on cases. Jack could visit for a family moment, reflecting their growth since Blue Bloods.
• Common Mistakes: Underusing Sean could waste a chance to explore Danny’s parenting struggles. Ignoring Jack might frustrate fans who want both sons included.
• Consequences of Errors: If Sean’s arc feels secondary or Jack’s cameo is rushed, it could weaken Danny’s emotional stakes. Fans on X have stressed Danny wouldn’t leave his kids behind.

Frank and Henry Reagan: The Patriarchs

Frank Reagan (Tom Selleck) and Henry Reagan (Len Cariou), the Reagan family patriarchs, are less likely but highly desired cameos. Selleck told Parade in December 2024 he’s open to returning as Frank, while Wahlberg hasn’t ruled out Henry.

• Why It Matters: Frank and Henry embody Blue Bloods’ moral backbone. A cameo could show Danny seeking their wisdom as he navigates Boston’s challenges.
• How It’s Done: A phone call or short visit could work, avoiding major disruption to Boston’s setting. Frank, as NYPD Commissioner, might consult on a cross-city case.
• Common Mistakes: Overusing big names like Selleck could overshadow new cast members like Ernie Hudson’s Reverend Peters. A cameo must feel organic.
• Consequences of Errors: A forced appearance could make Boston Blue feel like a Blue Bloods retread, risking its identity. Fans on X are split, with some wanting Frank, others wanting new stories.

FAQs

Why do fans want Blue Bloods characters in Boston Blue?
Fans crave cameos because Blue Bloods was about family—14 seasons of Reagan dinners built loyalty. Characters like Maria Baez or Jamie Reagan carry emotional weight, tying Danny’s Boston life to his New York roots. Without them, the spinoff might feel disconnected, like a new show wearing Blue Bloods’ skin. Wahlberg’s teases on Instagram, like his winking emoji for Baez, keep fans hopeful.

How will Boston Blue balance old and new characters?
Showrunners Brandon Sonnier and Margolis plan a “universe expansion,” not a rehash. Erin Reagan’s premiere cameo sets the tone—brief, impactful, and tied to Danny’s story. New characters like Lena Silver and Mae Silver must shine, or the show risks alienating viewers who want fresh stories. Overloading with Blue Bloods stars could dilute the Silver family’s arc.

Could too many cameos hurt Boston Blue?
Yes. Fans love nostalgia, but too many Reagans could make Boston Blue feel like a sequel, not a spinoff. X posts show some viewers want focus on the Silver family, not just Danny’s past. If cameos overshadow new dynamics, the show might lose its unique identity, especially with a strong cast like Sonequa Martin-Green and Gloria Reuben.

Will Maria Baez’s romance with Danny continue in Boston Blue?
It’s unconfirmed, but fans are hopeful after their Blue Bloods finale date. Wahlberg’s Instagram hints suggest Baez might appear, perhaps visiting Danny. If she doesn’t, fans might feel robbed, as X posts show strong support for their chemistry. A cameo must advance their story naturally, not force a romance.

Why is Erin Reagan’s cameo significant?
Erin’s guest spot in the premiere, announced in July 2025, links Boston Blue to Blue Bloods’ core. As Danny’s sister, she represents family ties. Her role as a director also adds creative weight. Fans on X are excited, but some worry it’ll overshadow new characters if not handled carefully.

Conclusion

Boston Blue is poised to carry the Blue Bloods torch, with Danny Reagan leading the charge in a new city. Fans are eager for cameos from Erin, Maria, Jamie, Eddie, Sean, Jack, Frank, or Henry, as seen in TV Insider’s August 2025 poll. These appearances must be thoughtful—Erin’s confirmed spot sets a high bar, but overloading with Reagans could drown out the Silver family’s story. Wahlberg’s teases and fan chatter on X show the hunger for connection, but Boston Blue needs to stand on its own. Will it deliver?
