The Littlest Winchester - Littlest Matchmaker
In many ways, Dean's four-year-old daughter takes after her father. She enjoys food, treats the Impala like a living creature, and is very defensive of her family, but more than almost anything in the world, she loves to be her uncle's personal pain in the ass. Sam attribute this to the way Dean eggs her on and dishes out generous amounts of positive reinforcement, and he secretly hopes she'll grow out of it, but knowing how Dean turned out, it isn't likely. Anyway, he can't exactly hold it against her when she gives him an honest-to-God hug, kiss, and 'I love you'. It's not the toddler's fault her father is an insufferable man-child.
