Are any of the Winchesters still alive?

As of my last knowledge update in October 2023, the Winchester brothers, Sam and Dean, are fictional characters from the TV series "Supernatural." In the show's final season, Dean dies during a hunt, and Sam eventually passes away from old age, implying that both brothers are no longer alive within the narrative. However, the series has a loyal fanbase, and discussions about potential spin-offs or alternate storylines often arise, so fans may still explore their legacy.
