Sherlock is upset at not knowing who the mastermind behind the Noahtic and Drebber cases is, and takes his frustration out on John. While returning by train from an investigation, Sherlock has a chance reunion with William.
You have to stop acting so frustrated
just because things didn't go your way.
عليك التوقف عن التصرف بإحباط فقط 
.لأنّ الأمور لم تكن لصالحك
also seien Sie nicht so gereizt, nur weil
es nicht so lief, wie Sie wollten.
Debes dejar de frustrarte tanto
Arrête de ronchonner
juste parce que tu es contrarié.
Precisa parar de ficar tão frustrado
Ну не оправдались твои ожидания, бывает.
Это не повод раздражаться.
