Great ep. Very emotional(last scenes). There was some action. There were few humorous scenes (Ottis and Mouch during making podcast).
I really hope that Voight thread(plot) is over.
And Severide should finally do sth, get busted or get a surgery for example.
about drug test
They found out about drug test after taking the pill by Severide.
Chief Boden ordered them to do it in the next scene.
