"Dammit Sammy!"
"Sorry Dean. Guess I'm still your Achilles Heel."
"No. You're my library-obsessed brother who reads too much. There's a difference."
Sammy was floored. "You know what an Achilles Heel is?"
Dean wasn't entirely sure, but he was about 98% sure. Maybe 95%...
"Of course! You're my permanent pain-in-the-ass brother who holds me back from my obvious talents as a playboy ."
"Close enough I guess. But you know, I can look after myself now Dean."
Dean eyed his brother from under the hood…. "uh huh"
"I can! And anyway, it doesn't matter."
""Why?"
"Because I'm going to college."
