Supernatural star Jensen Ackles reveals the advice he gave Brock Kelly for playing Dean

During a season 14 premiere screening and Q&A, EW talked to the actors about what flashbacks they’d like to see on the show, and furthermore, what advice they’d give (or have given) when it comes to playing Sam and Dean. Ackles recalled something he told Brock Kelly when Kelly played a teenage Dean in season 4’s “After School Special.” Ackles told Kelly to “Always play him tougher than he thinks he is,” Ackles said. “He’ll get there one day, but right now, he’s gotta fake it until he makes it. Be tougher than you think you need to be because then the vulnerable moments actually come out better.”

Supernatural airs Thursdays at 8 p.m. ET on The CW.
