"The guy on the left."

Conspiracy theory: S4E4: The Weight; Sil and Chrissy got to see Lou DiMaggio and the Atwell Avenue Boys in Rhode Island over that thing with the guy they know. DiMaggio's real last name is Galina, they started Calling him DiMaggio after he took a baseball bat to Lenny and his wife. Anyway, Sil hands one of Lou's guy a polaroid of Tony and "the guy they know" for the thing saying "The guy on the left." Now Lou's crew doesn't seem like the ripest tomatoes on the vine, being geriatric, blind, and crazy. Maybe they had a fugue state, recalled the job, found the photo, and boom. Hey, what are ya gonna do.
