On the desk at 12:40 you can clearly see a yellow coffee mug. The label reads: BIG HUG MUG. This is the same mug used by Rustin Cohle during his interrogation scenes of True Detective season 1, which was also directed by Cary Joji Fukunaga.
When Annie signs in at the psychiatric hospital to visit Owen, the name of the patient on the line above where she signs is "Wendy Lemuria," a reference to Wendy the lemur in episode 4, "Furs by Sebastian."
At one point, Owen asks Annie, "Annie, are you okay?" This is a lyric from chorus of the Michael Jackson song "Smooth Criminal".
