Mycroft:*sign*So you are alive, Irene Adler. Sherlock saved you, how unbelievable...
Irene: So I'm punished after these years? In this... isolated prison, shall we say?
Mycroft: I wish I can. But...As Sherlock wants to keep you safe, I won't.
Irene: So I should meet someone then.
Mycroft: Just five minutes.
Irene: I am a therapist or...?
Mycroft: A Christmas present.

Mycroft: You saved her.
Sherlock: Who?
Mycroft: You know who.
Sherlock: Voldemort?
Mycroft:...Don't be ridiculous. Irene Adler.
Sherlock: If you fixed your eyes on me you'll know the answer. So why you come here to ask me? You have MI5 and MI6.
Mycroft: Just to be clear.
Sherlock: Well, obviously. She said you've met her.
Mycroft: Dear Lord...And you still keep in touch?
Sherlock: And you made her as a Christmas present to Eurus.
Mycroft: She even told you that?
Sherlock: If you don't want me to know, don't let the Woman meet both of you.
Mycroft: Ohhhh... so you mean she's yours? And you'll protect her.
Sherlock: I didn't say it. It's all you imagination.
Mycroft:*sign*Just...
Sherlock: Stay away from her and don't disturb her. You don't want I save her again right?
Mycroft: Certainly.
Sherlock: Then don't find her. Keep her safe.
