The parallels between Bunny Colvin on the third season of the Wire and Glenn Close's character this season are there- both try unorthodox methods and, given the fact Glenn Close is leaving after this season, both will probably fail.

Still, even if Army gets taken out, and, given Glenn Close's departure from the show- unless she gets killed or something- I feel like the climax of the show has already passed. Meaning, I don't think anything coming up will really surprise me. I definitely don't think Shane is going anywhere either...
