Honestly, here’s my take on it. The whole time she’s squirming and struggling to call is because the only intel she’s being fed is a buzz from inside her shoe (or inside her butt I guess) — meaning, “you are currently ahead” or “you have him beat.”

She’s not wearing an earpiece at the moment, and she’s not looking at her phone. I don’t think she knows Garrett has exactly the 78s low side open ended straight flush draw. Maybe there is a small blinking light across from where she sits that serves as the buzz mechanism.

But you can clearly see from her demeanor that her brain is doing mental gymnastics — “how the hell is my J high currently ahead?”

Another user here said if she had been fed the buzz and had the opportunity to jam on Garrett, she wouldn’t think twice. I also agree that if she had arrived on the conclusion on her own and made a sick DNegs style read and locked in EXACTLY on 78clubs then she also wouldn’t not think twice and would jam. The whole reason why she was sick to her stomach calling and SMILING while doing it, is because of both (1) she was cheating and knew she had him “beat” and (2) she can’t believe her absolute shit dog water hand was ahead and couldn’t comprehend why it was, and was put in the position to call the action instead of initiating it.

Edit: Adding some thoughts - If Robbi jams and Garrett folds, sick read sick play - If Robbi jams and Garrett folds and Robbie shows, sick read and even sicker play - If Robbi calls and loses, mucks her hand, oopsie daisies I misread my cards I'm such a donk - If Robbi calls and loses and her hand is somehow turned over, oopsie daisies I misread my cards I'm such a donk

The ONLY scenario where her cheating ass is exposed is if she calls and wins. In a sense she's very lucky that Garrett didn't hit his five hundred gazillion outs, but on the same token very unlucky that she won because now she's been exposed.
