By John Keegan and Edmund BoysA funny thing happened on the way to “Burn Notice” adopting a whole new style of storytelling. The writers figured out they could use all the show’s familiar tropes to advance that storyline. As Team Westen methodically picks up the one or two bread crumbs that lead towards their goal, they recreate another classic situation from previous seasons. Previously, we actually saw Sam’s sugar mama, and a turf war was settled by pitting the two sides against each other. This time, Michael goes undercover with an attempt at a Boston accent, just to obtain Nate’s FBI file.
