Yes, simply walk up on her with your gun in hand

You step out of your hiding, rising the gun at Jo. Anne immediatly starts to cry again, begging Jo for forgiveance. Jo takes a few step away from you, looking in alarm at you and your pistol. Her eyes widen and you see her pale.

"What the he ...?" she stammers.

"Shut up, bitch!" you tell her, waving the pistol at her while closing in.

"If you do anything stupid I´ll shoot you. So shut up. I want your money and jewlery and whatever valueable you have. Then I´ll leave. So, don´t make me hurt you."

With this you stand in front of Jo, the gun pointing in her direction.

Jo stares in shock at you and your pistol. Her whole body is tensed and you see her thoughts racing.

"Just behave, little bitch." you growl at her.
