Why would Nick pull his gun on Juliette. If Juliette is mad does he really think pointing a gun at her is going to calm her down. If anything it would trigger a fear response and Nick would be dead.
Nick just saw Juliette take Hanks gun. So Nick think because it is him, Juliette would not take his gun. The women who when mad burnt up the trailer. The women who just threw her friend against a wall by holding her hand up. This is the women he points a loaded gun at. Did it ever cross his mind Juliette might make him eat that gun.
I wonder if he would have pulled his gun if he knew Juliette could blow his head off. the shot she mad Nick shot at Monroe did one of tow things. It either missed or Juliette stops it from hitting Monroe. As a missed shot it shows she can make him shot someone. If she catches the bullet it shows she can control Nick plus, she is faster then a speeding bullet.
How does Nick stop someone that can stop bullets. Maybe just maybe Nick should respect her power and try working with her. Instead after the spice shop Nick is going to be even more determined to control Juliette.
