How funny. . . for days, I couldn't think of a thing to say about the Third Noble Truth, but once I brought some mindfulness to it, I realized that by addressing the cessation of suffering - the whole promise that Buddhism holds out - it's actually about the very fulfillment of Siddharta's quest, it's about nirvana, it's the whole enchilada as it were, and I was overlooking the entire thing.
Live and learn.
