Finally, the lady gives up. Since she cannot obey her lord’s instructions to return to Edo with his family, she also cannot live with the offense of failing him. She will kill herself at sunset, she announces. Since Mariko is Christian, this is a mortal sin, unless she can find a second willing to deliver the death blow. It’s a grim honor — one that the Christian regent Lord Kiyama (Hiromoto Ida) refuses, despite his own beliefs. The lords are not yet ready to make a public break with Ishida and Ochiba, whose control of the Heir gives her incredible power.
But Mariko’s resolve gives her power of her own — a terrible sort of power. When Kiyama fails to show up at the ceremony to serve as her second, her ultimate reward for all this suffering seems to be the damnation of her immortal soul.
It’s all too much for Blackthorne to take. Grabbing a sword, he takes his place by her side, preparing the fatal stroke that will slice off her head after she thrusts a blade into her belly.
Ironically, this is one of the show’s most intensely romantic moments. Such is Blackthorne’s love for Mariko that he is willing to kill her in order to grant her death the honor she believes it will hold. Mariko believes she is damning herself to hell for eternity. Whether he also believes this is immaterial. He simply cannot allow her to experience that anguish in her last moments. He cannot let her die alone and afraid.
This fleeting but real emotional intimacy, profound beyond words, is conveyed by Cosmo Jarvis and Anna Sawai with minimal speech and movement. It’s all shown with their eyes.
