Jack Shepherd. Kate Austen. Sun-Hwa Kwon. Hugo Reyes. Sayid Jarrah. And a bald faced (bald headed?) lie known as Aaron Austen. These are the Oceanic 6, and these are the common subjects of the stack of newspapers on the tabletop of the booth where Ben sits. He's wearing his glasses, sipping a large cup of coffee, and jotting notes in a composition notebook.
If asked, he'll just answer that he's catching up on old friends. (Specifically, he's trying to catch up on Sayid.)
