Detective Charlie Hudson is one of the central characters in Hudson and Rex, and in Season 7, his absence has puzzled many fans. This was due to both storyline adjustments and personal circumstances in actor John Reardon’s life.
In the show, Hudson is away on a mission to find his brother, which explains his absence within the plot. Off-screen, Reardon was diagnosed with tonsil cancer when Season 7 began filming, prompting him to step back from production for treatment while the writers adjusted the script accordingly.
Why is Charlie Hudson missing from several Episodes in Season 7 in Hudson and Rex

As explained, when Season 7 of Hudson and Rex started shooting, John Reardon was diagnosed with tonsil or throat cancer. This serious condition, along with the show’s narrative—where he is away on a mission to look for his brother—resulted in his absence from several episodes.
Reardon stepped back from production to focus on treatment while the writers adjusted the script accordingly. His reduced screen time is therefore due to medical leave, not solely a creative choice.
Season 7 of Hudson and Rex premiered on July 10, 2025, and is wrapping on August 28, as per IMDb.

Reports confirmed that fans expressed strong support for him, sending well wishes and recovery messages. According to the latest news, the actor’s treatment was a success, and he is now cancer-free.
On Instagram, Reardon thanked fans for their encouragement and announced he had been cleared to return to work, writing:
"Missing #newfoundland and all my friends on 'Hudson & Rex.' It was hard not to be there with them while they continued to make the show great! I am happy to say though that I am cancer free and have been cleared to go back to work in full capacity! Feeling strong and very appreciative. I am overwhelmed by the response I’ve had from fans around the world saying how important the show is to them and the well wishes. The show has truly been the dedication of my last 7 years as well as my family’s who continue to support me in the endeavor to bring you more shows."
His message suggests Hudson will return in Season 8, though City TV has yet to confirm whether that will happen, leaving the decision to Reardon’s interest and the network’s plans.
