Make a Movie 廿

I know simple scenes are usually better, but sometimes I find I have to write a scene that involves lots of speech or detail in order to get the feeling of the interaction across to me. I never really remember the whole scene or the exchanges word for word, but I can then remember the facial expressions or overall scene vibe much better:

Nigella Lawson is having an archery competition of sorts with Howl in his bathroom. She is annoying him by narrating out loud the whole time. Two targets are set up over the bath and they are aiming at them with a broomstick. "Now, at night, what I love the most after sneaking into the kitchen to eat brownies, is to then come into the bathroom and throw broomsticks as targets..." She says.
Howl looks around, confused at who she's talking to.
"and..." she continues "I always hit a perfect twenty on my first go!"
She hurls the broom stick at the targets, which clatters sadly to the floor between the two targets. "She?" She smiles smugly. "Perfect twenty!"
Howl makes a sound in his throat and Nigella smiles lazily. "I know darling! I'm fabulous!" Howl pokes her cheek "Are you drunk?"

You can also say 二十, right? Does this way sound, like, less normal in Chinese than 廿?

Natalie Portman stands with a machete in front of 2 crucifixes side by side, she's declare that one of the condemned gets to go free. One offers her $20, she accepts and chops the crucifix down at the base.
