One of the most affecting, well-acted scenes in The Final Problem arrives near the middle of Euruss elaborate experiment. In a series of tests seemingly designed to determine how effectively Sherlock has choked off his emotional life, Eurus forces him to make choices that will result in devastation and death. This one, though, requires no bullets or death sentencesEurus forces Sherlock to get Molly Hooper to say the words I love you, and if he doesnt succeed, shell die.
Its an emotionally rich and nuanced scene, and features some of Louise Brealeys best work as Molly. Its arguably Cumberbatchs best scene in the episode as wellhe balances fear and anger with shame, sorrow, and remorse. Her refusal to pick up the phone stings. Her acknowledgment of his cruelty hits still harder. Her insistence that he say those words first, and his first forced attempt gives way to a devastatingly simple one thats ripe with the aforementioned ambiguity these writers do so well, when they so choose. Its a gripping scene with an ending that cuts deep: of course there was no bomb. Sherlock just wrecked that poor woman, and himself, for nothing.
And thats it. No consequences. It hurts, but doesnt linger. So what if it relegates a character, once again, to the position of lovelorn girl friday? Weve got to get on to the next epic set piece.
The biggest issue with Sherlocks typically brief fourth season is exactly that: nothing seems to stick. By episodes end, Mollys skipping in the door with a smile on her face; whether shes arriving in response to a message Sherlock sent to a person unnamed, well never know. Theres no price to pay for years of mistreatment capped off with a doozy of a phone call like that.
