Jack Kline: I just don’t want Sam and Dean and Cas to worry.
Donatello Redfield: They’re your family. Families worry.
Jack Kline: But I just… I need time and space to figure things out on my own, but everywhere I go, there’s someone looking over my shoulder.
Donatello Redfield: Ah. When I need to, uh, “blend,” I ask myself, “What would Mr. Rogers do?”
Jack Kline: Who’s Mr. Rogers?
Donatello Redfield: The best man I know.
Jack Kline: Sam and Dean are the best men I know.
Donatello Redfield: So, ergo, whenever you don’t want them to worry, just think “WWWD”… “What Would the Winchesters Do?”
Jack Kline: I can do that.
