Hi Joel! Here's a fun thing to think about as you work your way through this season. It always seems like the primary movers on each side have some parallel characters on the other. McNulty and D'Angelo both think out of the box and ask some similar questions about the broken institutions that they serve. At the same time, D'Angelo's position, to some degree, depends on his blood relationship with his uncle Avon--not too dissimilar from how Prez has held on to his job; both of them get a pass that nobody else would have after demonstrating that they might not quite be made of the same stuff as more sucessful players. Nepotism and patronage are both huge theme in this show.
