Supernatural! I love all these touching theories about the Winchester boys. And...can I just say I love the image from Iron Giant, haha! So great, it sums up my feelings perfectly. LOVE that movie too :D
There are a million instances, but just watched 10x09 where Sam tries to hold on to Dean's humanity and never let him go!
By the seasons go on their happiness and innocence go away piece by piece but sammy hair gets longer and longer
