As Boston Blue has worked to establish itself both within the Blue Bloods universe and in its own right as a series, the show has managed to avoid most conflict within the universe, but in a recent episode, a noticeable plot hole finally opened up. With established characters making up part of Boston Blue's cast, the series has been able to take Donnie Wahlberg's Danny Reagan into a whole new world, moving him from his life in New York City to a completely different space in Boston. Boston Blue has featured characters from its parent show, but has tried to develop its own world, too.

While Danny didn't move to the new city entirely alone, the majority of Blue Bloods characters didn't jump over to the new series permanently. Instead, Boston Blue has featured guest appearances from several members of the Reagan family, and brought Maria Baez (Marisa Ramirez) on as a recurring member of the cast to round out Danny's home life. The impact of seeing characters from Blue Bloods on Boston Blue has been largely positive, drawing enough from the original series to establish a similar tone, but ensuring that new characters, like detective Lena Silver (Sonequa Martin-Green), are able to ground the new world.

Although bringing characters over from Blue Bloods has been an overall positive experience, the series has finally hit a snag in working with the established world of the 14-season CBS series. During the most recent Reagan visit, when Jamie Reagan (Will Estes) came to town, Boston Blue season 2 saw the show's first noticeable plot hole rip open.

Jamie Incorrectly Refers To Joe In Boston Blue

Although seeing Jamie return to the Blue Bloods universe in Boston Blue season 2 episode 5, "Blood Diamonds," was exciting, it also brought a plot hole that's been plaguing the franchise back into play again. While the birth order of the Reagan children has long been something that the show itself has played around with, the original establishment of their ages on Blue Bloods saw Danny as the eldest son, followed by Erin (Bridgen Moynahan), then the late Joe Reagan, and finally Jamie. Later in the series, Blue Bloods switched Joe to being the eldest Reagan brother to support his son, Joe Hill (Will Hochman) coming into the picture.

Most Blue Bloods fans consider Danny to be the oldest, disregarding the birth order change later in the show's run, but during Jamie's appearance on Boston Blue, the issue came up again. During a tense moment, Danny explained that he and Jamie "lost our older brother, Joe," despite the fact that he is meant to be older than Joe in the family birth order. While the series simply seems to be perpetuating the change that Blue Bloods put into play, the fact that the series is still trying to push the narrative that the retroactive swap is accurate makes for a major plot hole.

Will Jamie Come Back To Boston Blue Moving Forward?

Although the inconsistency of the family birth order is frustrating, seeing the Reagan family together on screen is exciting enough to smooth it over and move forward. Jamie's appearance on Boston Blue re-established his relationship with Danny in a way that made it clear that there need to be more visits from the Reagan siblings in Boston, especially with the roots their brother has put down there. Boston Blue season 2 episode 5 established how much has changed for Jamie since the end of Blue Bloods, and his newfound fatherhood to his son with Eddie (Vanessa Ray) could see him reaching out to his older brother more frequently.

While Estes opened up about how difficult it was to return to Jamie's shoes after playing him on Blue Bloods for so many years, the ease with which he was able to embody his character was clear on Boston Blue. The door clearly remains open for future visits from Jamie, especially if he brings Eddie and their young son along for the ride the next time he returns to the series. While his visit to Boston Blue was a one-off for now, it's absolutely possible that he'll be back for another episode in the future of the CBS spinoff series.
