As he said, a simple “thank you” wouldn’t seem like enough to cover everything that happened behind the scenes or with the fans, who have formed one of the most devoted fandoms in the world.
Ackles can take some comfort, though, in the fact that his “ride” can continue a bit, seeing as how his memories of Supernatural will be joined by his actual possession of Baby, the famed Impala that Sam and Dean traversed the country in.
Man, I’m sure we’ve all had days where we wake up and are suddenly faced with the renewed realization that “this is it” and something big is set to go down, so I get where Ackles is coming from.
