I'm still convinced after rewatching this scene that these two are related. The writers went out of their way to show her hostility towards him in the first episode. It would make sense for her to stab him out of annoyance. For me it's either that or Chanel #3.
And her line tonight about going home would make sense for her to be home with her brother and Gigi during that scene. Plus her name is Chanel #5, she has an iconic perfume named after her. Her number is not simply random.
