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.
I have found him looking glum and
brooding more and more frequently.
.أصبح مكتئبا ويغرق في التفكير أكثر فأكثر
war Sherlock immer öfter mit
bedrücktem Gesicht in Gedanken versunken.
lo encuentro triste y distraído
con más frecuencia.
je le trouvais de plus en plus
abattu et préoccupé.
mais eu o vejo desanimado
e cada vez mais inquieto.
он... стал мрачнее тучи,
 захваченный своими мыслями.
