Here are mine :

Moriarty : Welcome to the final problem.

Sherlock : Hey, bro !

John : There's a place for people like you, the desperate, the terrified. The ones with nowhere else to run.
Mycroft : What place ?
John : 221B Baker Street. If there's a queue, join in.

Mycroft : Every choice you ever made, every path you've ever taken, the man you are today is your memory of Eurus.

Mycroft (BAMF !!) : For your own physical safety, do not speak. Do not indulge in any non-verbal signals suggestive of internal thought !

Mycroft : I presume the tapes are in my office ?
Governor : Your office ?
Mycroft : Cast your mind back. Used to be yours.

Sherlock to Mycroft : Do shut up, dear.

Sherlock : He's trying to make it easy for me to kill him.

Mycroft : I promised my brain to the Royal Society.
Sherlock : Where would you suggest ?
Mycroft : Well, I suppose there is a heart somewhere inside me. I don't imagine it's much of a target, but why don't we try for that ?

Mycroft : Goodbye, brother mine. No flowers. My request.

Moriarty : Holmes killing Holmes.

Mary : PS : I know you two. And if I'm gone, I know what you could become. Because I know who you really are. A junkie who solves crimes to get high. And the doctor who never came home from the war. Will you listen to me ? Who you really are, it doesn't matter. It's all about the legend. The stories, the adventures. There is a last refuge for the desperate, the unloved, the persecuted. There is a final court of appeal for everyone. When life gets too strange, too impossible, too frightening, there is always one last hope. When all else fails, there are two men sitting arguing in a scruffy flat like they've always been there, and they always will. The best and wisest men I have ever known. My Baker Street boys. Sherlock Holmes and Doctor Watson.

Honestly Mycroft needs a John, too! (there is someone who would come to my mind )

Are you, by chance, thinking about a certain DI ? If so, he was asked by Sherlock to take care of Mycroft...

I have been in love with Mycroft Holmes since the series began, and my love for him grew exponentially as the series progressed. The Final Problem was an absolute dream come true for me for many reasons. One of which, was the character development we got to see for Mycroft Holmes. He finally feels human.

​Just to highlight a few key Mycroft scenes from this episode:
​1. It was lovely and hilarious know that he's corny at heart. Watching a racy, romantic film noir on a projector, all by himself; mouthing the lines because he's watched it so many times. Too damn cute. It's okay, Mikey. You'll get a girlfriend/wife soon enough (I hope so).

2. The childhood videos, photos and flashbacks of fat Mycroft. How adorable!
​
3. The grenade scene between him, Sherlock and John Watson was thrilling and absolutely hilarious at the same time. Them staying absolutely still while deciding what to do was so funny and genuine. Mycroft's references to him playing Lady Bracknell throughout the episode had me in tears laughing.

​4. Mycroft disguised as the ship captain. I guess all the Holmes siblings are great at completely transforming themselves, in terms of their accents and mannerisms.

​5. Mycroft's rage-fit towards the governor (incredibly hot).

​6. Mycroft's general reaction towards the atrocities that Euros was committing before his very eyes. He seemed to be the most human of the 3 (him, Sherlock and John), but that's plainly because he isn't as experienced as Sherlock and John when it comes to handling such high pressure situations. Sherlock and John clearly have nerves of absolute steel; true heroes. Mycroft was visibly disturbed by what was happening to them and even gagged when the governor shot himself. This is a side of M. Holmes we haven't seen before - a very vulnerable and horrified Mycroft Holmes. Phenomenal acting from Mark's part.

​7. Mycroft got owned in this episode. W
