As we all know that at one point Boston ask Maggie "Have you seen this boy"
 
 I know it is a point of the game where Brink disappeared
 
 I have played the game lately and I tried it lots of time to find out.
 
 But I had no success.
 
 So, does anyone know at what point EXACTLY you can hear this phrase?
 
 thx
  
 
  
  
    I ask myself the same thing. I really don't know where to activate that line.
  
 
  
  
    I found the part of the game, where Boston says this line:
 
 When Brink dissapears the first time (on the museum island), visit Maggie in the library and talk to her.
 
 When you talk about Brink, he will say this line.
