She is so easily manipulated & simultaneously so confident in her own pseudo-Machiavellian machinations.
When Nader triggers her rage - this time, with the (hopefully simulated) BJ on-screen between himself & DD - she instantly goes live to spin (another) lie, changing the details of prior stories (again) she’s told to match her current need.
We’re supposed to blindly believe: She and motorcycle guy fucked in her car. Yep! Sex in her tiny, filthy, shitty car…between her and a tall, big man? Totally happened, because Nader got a BJ so of course she got laid. She’s one step better in her mind, and irrationally assumes people actually believe this shit.
Should Nader claim to bed twins, she’d breathlessly amend a prior lover into triplets.
“Did I ever tell you guys this before?” She questions. Eyes darting side to side, desperately trying to recall details of prior lies that her alcohol & drug soaked brain can’t provide.
“Oh, I told you some of it…” She handwaves, trying to get a feel for what lies she’s told before and mesh them into this current iteration of the story while also erasing any indication she gave before that that was the be-all and end-all truth.
Chantal feigns coy and proudly states she urinated in the bed of a female foe, blissfully unaware how utterly transparent (and repugnant) she is to anyone with room temperature IQ.
ETA: re: Google Pay has her credit card info saved, in Nader’s phone. Those purchases could be for anything, because you can shop nearly anywhere with Google Pay. I’m just shocked it’s only $1200, but that’s likely all the available credit she had
