As Kujan stares at the bulletin board he drops his coffee mug, which shatters on the floor. But breaking this mug achieves a major breakthrough: Kujan sees that brand name on the fragment from the bottom of the mug reads, “Kobayashi”. Moments after letting Kint go, Kujan realizes that his story was one big fabrication, and that Kint is in fact none other than Keyser Söze. As Söze escapes, he gets into a car driven by “Kobayashi”, and they disappear. McQuarrie’s script specifies that two of the words are seen by us but not by Kujan, who obviously has already basically figured things out and is in too much of a hurry to notice all of it. Those are the two words printed on the porcelain fragment that was the bottom of the cheap mug Kint had drunk coffee from: KOBAYASHI PORCELAIN.
The shattered ‘Kobayashi Porcelain’ cup which at last prompts Kujan to solve the mystery of Keyser Söze.
