do wewe known why meg calls castiel "clarence"..for me, it's a riddle...i want to known why..please

It's a reference to an old movie titled "It's a Wonderful Life," in which there is an Angel named Clarence that comes down from Heaven and helps out a guy named George realize his worth and how many lives he has changed and affected just kwa being born.

I believe that Meg calls Cas "Clarence" because the Angel that earned his wings helping Jimmy Stewart in the movie "It's a Wonderful Life" was named Clarence and after all Cas is an angel.

Have wewe ever seen the movie "Its A Wonderful Life" At one point Cas basically says he doesn't understand what she is referencing and she says that he should really watch a movie.In the movie, there is an Angel names Clarence.

Clarence is an Angel from "It's A Wonderful Life". He is a guardian Angel to Gorge Bailey who has aliyopewa up his dreams in order to help others, like Dean and Castiel's relationship. That's my theory, Hope it helped!
