In Supernatural, viewers have followed the adventures of the Winchester brothers as they battle demons, angels, and other supernatural creatures. Their relationship is one of the main drivers of the plot, and it was clear from the first season that Dean always felt responsible for his younger brother.
Sam, on the other hand, has often strived for independence, trying to find his own way in life. This dynamic is largely explained by the age difference between them. But what is it?
Dean is four years older than Sam, which is a key moment that defines their characters. As a child, Dean had to grow up early to take care of his younger brother after the tragic death of their mother.

Interestingly, the actors who played the main roles have the same age difference: Jensen Ackles (Dean) was born in 1978, and Jared Padalecki (Sam) was born in 1982. This detail adds additional credibility and depth to the Winchesters' story, as their interactions on screen seem completely natural.
