I absolutely loved this blink-and-you’ll-miss-it moment in After School Special. Even though Dean had this “cool kid” reputation, he still thought about Sammy before anything. Even after just making out with a hot girl, he just had to let his baby brother know he saw him, that he was right there.. the second he laid eyes on him. Just to see his face and make sure he was okay. You can actually see the nod of confirmation on Dean’s face after Sam looks at him. It just took this small little gesture to perfectly encapsulate Dean’s love for Sammy. Most big brothers would be embarrassed, or just wouldn’t really care. But not Dean. Because that was his whole world walking through that hall, and just his simple “yo, Sammy” and a smile was enough to prove it.
