After MacVe was reborn, the first thing he did was to call and flirt with the factory girl.
The second thing is to call that bad brother.
Sherlock: The documents on the table were brought here this morning. You only looked through two or three of them. The tea snacks next to you didn't move much. You shouldn't have gained three pounds a month. What's even more special is that you didn't say a word when you called me over, and looked at me eight times with pity. Obviously, you know some interesting things about me through some channels that are inconvenient to tell you.
Mike: It's really interesting... Did you know that sometimes love is a kind of fulfillment?
Sherlock: I don't think I need to remind you that you should know that it is impossible to love as a high-functioning sociopath.
MacVe: But the fact is that you let go and fulfilled a person, and you ended up alone.
Sherlock: ... I hate this kind of joke.
Mike: You and I both know that's not the case.
