Hudson and Rex Season 9 Plot Explained: Charlie Hudson Returns in 2026 After Major Fan Backlash
Hudson and Rex is heading into Season 9 with a problem it cannot simply solve by introducing another murder case. Charlie Hudson is back, and after the way Season 8 handled his absence, his return carries a lot more weight than a normal character comeback. Citytv and Shaftesbury have confirmed a 12-episode ninth season, with John Reardon returning as Detective Charlie Hudson alongside Rex, the German Shepherd who has been at the center of the series from the beginning.
The reaction from viewers played a major part in making this return such a big story. Fans spent months arguing about the direction of the show across Reddit, Facebook groups, YouTube, and other online communities. The criticism was not really about wanting the same story forever. It was about the loss of the relationship that gave Hudson and Rex its identity: Charlie and Rex working together, trusting each other, and solving cases almost as much through instinct as police procedure. Season 8 replaced that setup, and a sizeable part of the audience did not warm to the change.
Why Charlie Hudson Left
John Reardon temporarily stepped away from the series during Season 7 while undergoing treatment for tonsil cancer. He completed his treatment successfully, but instead of simply building his return into the next season, the writers took the story in another direction. Season 8 introduced Luke Roberts as Detective Mark Hudson, a veteran with experience in military canine units and the Halifax Police Department.
The explanation for Charlie’s absence was that he had left St. John’s and travelled to South America while searching for his missing brother, Jack. As the season went on, the details became increasingly grim. Characters began talking about Charlie as though he might never come back, with hints that his search in the Belize wilderness could have ended in his death. It was a bold way to write around Reardon’s absence, but it also created a problem the series could not ignore.
Charlie was not just another detective who could be replaced. His partnership with Rex was one of the show’s defining relationships, while his connection with Dr. Sarah Truong had been building its own emotional history. Removing both elements at once left Season 8 feeling noticeably different, even when the individual cases followed the familiar procedural formula.
Charlie Is Coming Home
The Season 9 story begins with the moment fans have been waiting for: Charlie walks back into the St. John’s Police Department alive. There is no easy reset button, though. He has spent months in South America, and he is not returning simply because his old job is waiting for him.
Charlie still has one secret task to finish before he can put the Belize mission behind him. That unfinished business becomes one of the season’s main story arcs, linking his brother’s disappearance to the people and circumstances Charlie encountered during his unauthorized investigation. The show can now use the case to answer questions that Season 8 deliberately left hanging while giving Charlie a reason to remain emotionally guarded.
His return also creates an awkward problem inside the police department. Mark Hudson did not simply occupy Charlie’s desk for a few episodes; he developed his own working relationship with Rex and established himself within the unit. Luke Roberts is staying with the main cast for Season 9, so the series is not pretending Mark never happened.
| Character | Season 9 Situation |
|---|---|
| Charlie Hudson | Returns from South America and continues investigating his brother’s disappearance |
| Rex | Reunited with Charlie but still has a professional bond with Mark |
| Mark Hudson | Remains with the team and works alongside Charlie |
| Sarah Truong | Faces the emotional fallout of Charlie’s unexpected return |
| Jesse Mills | Helps deal with the practical problems created by the new team dynamic |
| Joseph Donovan | Has to manage the friction between the two detectives |
That gives Hudson and Rex an unusual setup. Rex now has two detectives in his orbit, and neither man is likely to be happy about sharing the partnership. Charlie relies heavily on instinct and personal connections, while Mark’s background has given him a more disciplined, structured approach. The contrast could be fun when the show lets it breathe, although it will also be important not to turn the rivalry into a repetitive gimmick.
Sarah and Charlie Have Some Repair Work to Do
Charlie and Dr. Sarah Truong have another problem waiting for them, and it is much harder to solve with police work. Sarah believed Charlie was gone. She had to deal with his apparent death while he was thousands of miles away pursuing his own mission, and now he has suddenly returned to her life.
Mayko Nguyen has indicated that Sarah’s reaction will not be simple happiness. Relief is there, but so are anger, confusion, and the emotional distance created by Charlie’s disappearance. That makes sense for the character. The series would lose some of its credibility if Sarah simply smiled, hugged Charlie, and went straight back to where their relationship stood before he left.
Their reconciliation is therefore expected to move slowly. Charlie has spent a long time keeping people at a distance, and Sarah has her own reasons for not immediately trusting him with everything she feels. For viewers who have followed their relationship from the earlier seasons, that unresolved tension may be one of the more interesting parts of Season 9.
Elsewhere, Jesse Mills and Superintendent Joseph Donovan have to deal with the less romantic consequences of putting two very different detectives in the same unit. Donovan, in particular, has to keep the department functioning while Charlie’s intuitive style clashes with Mark’s military-influenced approach. The conflict could add some welcome friction to the police-side stories without taking over the show.
The Procedural Formula Is Still There
For all the serialized drama surrounding Charlie, Hudson and Rex is not suddenly becoming a completely different series. Season 9 still has plenty of standalone investigations, unusual murders, action sequences, and the Newfoundland setting that has become part of the show’s visual identity.
The early episode material suggests that the writers are not easing viewers back in. One case centers on the murder of a professional wrestler shortly before a major charity event. The investigation takes Charlie and the team into the local wrestling scene, where professional rivalries, backstage grudges, and personal conflicts quickly muddy the search for the killer. An animal shelter also becomes caught up in the case, giving Rex a reason to be involved beyond simply following suspects around.
Another episode focuses on the death of an art instructor who falls from a seaside cliff during an outdoor painting class. The circumstances make it look like an accident, but the investigation suggests there may be more going on. It is exactly the kind of case the series has always handled well: an apparently straightforward death that becomes stranger as the detectives start talking to the people who were there.
That balance will matter. The Charlie storyline gives Season 9 a stronger continuing arc, but the show still needs its weekly mysteries to work on their own. If the personal drama overwhelms the cases, Hudson and Rex risks losing the simple procedural charm that brought viewers back season after season.
Rex Still Has Plenty of Work to Do
The production is also continuing the complicated process of bringing Rex to life on screen. Canine coordinator Sherri Davis oversees the training, with several German Shepherds sharing the role.
After the death of the original canine star Diesel vom Burgimwald, the production turned to Diesel’s relatives. His nephews Dillon and Dante, along with his cousin Dreamer, continue to handle much of Rex’s work. Izzy and Iko are used as stunt doubles for the more physically demanding sequences, including chases and rescue scenes.
That arrangement matters because Rex is not treated like a simple prop or mascot. His reactions often carry scenes that would otherwise require pages of dialogue, and the different dogs have to maintain the same recognizable behavior and screen presence. It is one of those behind-the-scenes details viewers may not notice while watching, which is probably a sign that the training is doing its job.

When Does Hudson and Rex Season 9 Premiere?
Season 9 is scheduled to premiere in Canada on Citytv and Citytv+ on Monday, October 5, 2026, at 9/8c. In the United States, Hudson and Rex continues to air on UPtv and stream through UP Faith & Family.
American viewers are currently working through Season 8, which premiered on U.S. cable on August 6, 2026. The U.S. release of Season 9 is expected to follow the Canadian run, although viewers should keep an eye on UPtv and UP Faith & Family for the confirmed schedule.
The bigger question is not whether Charlie is back. We already know that. The interesting part is what the show does with him now that the reunion has happened. Charlie cannot simply walk into the station, whistle for Rex, and pretend the last season never existed. Sarah has feelings to work through, Mark has earned his place on the team, Rex has formed a second partnership, and Charlie still has unfinished business from Belize.
That gives Season 9 a chance to make the most of the disruption that caused so much frustration in the first place. The return of Charlie matters because of what the character means to Rex, Sarah, and the structure of the series, not simply because viewers missed seeing John Reardon on screen. If the writers let those relationships carry some genuine consequences, the season could make the comeback feel earned rather than like a quick correction to an unpopular storyline.
