“Silence Of The Night” forced Atwater to work with the racist cop, Doyle, who pulled a gun on him back in Season 6.
Atwater, being Atwater, told the truth.
Voight promised that he and Intelligence all have his back, and the hour ended on a suspenseful note with Doyle’s people making a show of force on Atwater.
Also, Upton and Halstead were cute together for half a scene before everything went sideways.
