So first you have to put Arianna off-screen.
@ARIANNA spot 1.280 220 31 in zone 1
And then you have to make her walk to the spot.
@ARIANNA walks to spot 1.280 68 14 in zone 2 AND ARIANNA faces right
And if you continue the line above with AND ARIANNA starts idle_handsonhips_neutral_loop AND ARIANNA moves to layer 6 she will be floating in with her hands on her hips, so this is how you want the script to look like:
INT. BAR - DAY
&zoom reset
&cut to zone 2
&LUCAS spot 1.280 255 47 in zone 2 AND LUCAS faces left AND LUCAS starts think_rubchin AND LUCAS moves to layer 7
@ARIANNA spot 1.280 220 31 in zone 1
@ARIANNA walks to spot 1.280 68 14 in zone 2 AND ARIANNA faces right
@ARIANNA starts idle_handsonhips_neutral_loop AND ARIANNA moves to layer 6
ARIANNA (talk_handsonhips_neutral)
Well look who it is
@ARIANNA is idle_handsonhips_neutral_loop
LUCAS (talk_think_neutral)
Aria. Do my mum and dad know you’re here
ARIANNA (talk_armscrossed_neutral_loop)
Question is do they know you’re back in town
@ARIANNA is idle_armscrossed_neutral_loop
LUCAS (talk_shrug_neutral)
They do.
I hope that helped!
