I was watching some of season 6 last night and remembered something that never really was clear to me.
When Sayid kills Dogan, Lennon comes in the room and says that he (dogan) was the only thing keeping the smoke monster out. Then of course Smokey comes rolling through killing everyone.
Does anyone understand why this is? They make a point earlier in the episode to show the circle of ash around the temple before Flocke sends Clair in. Why would Dogans life be keeping the smoke monster out?
