BBCSherlockis in the company of the mostsuccessful retellings of Arthur Conan Doyle’s original stories. Written by Mark Gatiss and Steven Moffat, the series scored four seasons, one special, and one mini-episode, and was somewhat of a phenomenon for audiences globally. With creative liberty on the rights of Sherlock Holmes, the television series modernized the infamous detective, and its popularity raisedtalks for a BBCSherlockrevivalyears after the finale. However,Sherlockseason 5 is more difficult because of one perfect line from the final episode.
Benedict Cumberbatch and Martin Freeman were the stars of the British series, but the ensemble cast acted as a crucial buffer against Sherlock and his antics. It would not be difficult to recognizeSherlock’s immense debt of gratitude to Scotland Yard’s Detective Inspector, Greg Lestrade (Rupert Graves). Lestrade features in a very small number of Conan Doyle stories, but his character is instrumental to the development of Sherlock’s character in the modern adaption, from season 1 up until the final episode, where he provides a comment that serves as a perfect ending to Sherlock’s story.

Sherlock’s Last Episode Gave Sherlock Holmes A Perfect Full Circle Moment
Detective Inspector Lestrade Delivers 2 Lines That Make Season 5 Unnecessary
Season 1, episode 1, “A Study in Pink,” establishes the working relationship between Greg and Sherlock, and signals Lestrade’s faith in the wayward detective through the belief that “Sherlock’s a great man, and perhaps one day if we’re lucky, he might be a good one.” The show ends in season 4, episode 3, “The Final Problem” with an officer honoring the detective as a great man after a dangerous encounter with his estrangedSherlock’s estranged sister, Eurus, to which Lestrade replies, “He’s more than that. He’s a good one.”
The Silliest Scene In BBC’s Sherlock Is Why I Liked The Benedict Cumberbatch Show So Much
Although it was mostly a drama TV show, the BBC’s Sherlock had its silly moments, and one, in particular, shows why I like the show so much.
Thesetwo lines aloneprovide the overarching basis for Sherlock’s character arcand act as bookends to the whole story. The person that Sherlock was at the beginning of the show could not be further from who he became as a result of the friendships he built through the experiences and the challenges he faced. Lestrade’s final line ties togetherSherlock’s ending neatly. Beyond any doubt, a continuation of the chronicles for a fifth season would plainly spoil the finale, as it would make redundant the culmination of efforts put intoSherlock’s ending in the series finale.

Lestrade’s Line Highlights Sherlock’s Character Development Throughout The Series
Sherlock Holmes Was A Far Better Person By The End Of Sherlock
Season 1 ofSherlocksets the foundations for a cold and emotionally detached protagonist who, in all honestly, makes the character rather difficult to root for. His social ineptness comes across as ill-mannered, which is perhaps most evident in his association with mortician, Molly Hooper (Louise Brealey).Towards the beginning of the series, Sherlock makes calculated commentsto rebuff the girl’s affections towards him. By the end of the series, the detective is seen to be in emotional distress during a situation where he’s forced to cause emotional affliction towards Molly at the hands of his sister’s demands.
The concluding line demonstrates the extent of challenges Sherlock goes up against, and calls to attention the magnitude of his growth.

At the end of the show, the detective was able to show empathy towards others innately, but more importantly, in the friendships that he eventually came to value far more than the work. Lestrade’s final line, “…He’s a good one,” highlights Sherlock’s full characterization throughout, and the progression towards him becoming a better, more considerate, human being. Greg’s first conjecture towards the detective was hesitant, believing the man could only strive for better “one day, if we’re lucky.” The concluding line demonstrates the extent of challenges Sherlock goes up against, andcalls to attention the magnitude of his growth.
Sherlock Couldn’t Have Become A “Good Man” Without Lestrade
Greg Lestrade’s Unwavering Support Was Vital For Sherlock’s Growth
Detective Inspector, Greg Lestrade, is the one character in Gatiss and Moffat’s narrative whose trust in Sherlock Holmes has never wavered. On numerous occasions, even close friends such as Watson (Freeman) are seen to lose their temper because of Sherlock’s behavior. However, Lestrade frequently remains entirely unfazed by Sherlock’s grandeur, even in moments that compromise the Scotland Yard employees' credibility. It is clear throughoutSherlockthat solving London’s crimes is far more important to Lestrade than his own pride, andthis type of grounded nature is exactly what Sherlock neededto become a better person.
Arguably,Lestrade’s compassion for Sherlock inclines itself towards paternal at times. Moments such as season 3, episode 2, “The Sign of Three,” convey this well - the Inspector does not hesitate to lose out on the biggest case of his professional career, so that he could use his resources for backup at Baker Street when he thought Sherlock was in danger. Lestrade is admired by the audience because he is so similar to them, just if everyone was the best version of themselves they could be. Without Lestrade’s constant encouragement, Sherlock wouldn’t have had the opportunity to become “a good man.”
