Watson is only just starting out Season 2 in the fall 2025 TV schedule, but the doctor-detective drama already delving even further into Sherlock Holmes lore with the man himself debuting in the premiere. It's a safe bet that John will be much happier to see Sherlock's return from the dead than he was the now-deceased Moriarty in Season 1. That doesn't mean a straightforward reunion for the old friends, however. Ahead of his first full episode on October 20, Robert Carlyle spoke with CinemaBlend about taking on the mantle of the legendary detective and his reunion with Morris Chestnut's John Watson.
Carlyle technically made his Watson debut in the Season 2 premiere, available streaming now with a Paramount+ subscription, but his first full episode airs on October 20 to shed light on where Sherlock has been all this time. Appropriately called "Back From the Dead," it features Watson catching up with his old friend while he and his team work on a "zombie virus" that could wreak some serious havoc.
