Not sure if this theory was ever discussed much but it makes the most sense to me after rewatching the hand.
tl;dr
- Persson is sitting right next to Garrett and may well be able to see Garrett's hand when he peels his cards
- Persson displays a lot of suspicious behavior during and after the hand, including potential signalling with his lips and face
- When Robbi asks Garrett whether he wants her to call, Persson says "I vote no", and she calls basically straightaway (!)
- Persson looks nervous after the hand when Garrett gets suspicious and keeps trying to back up Robbi as she tries to explain her play.
- Persson looks like he tries to glimpse Garrett's hand in the very next hand and covers it by taking a drink
Timestamps
2:15 - Persson slowly peels his cards as though he is waiting for Garrett to peel his cards, and pinches his lips to his left. His eyes are obscured by his hat but he could be looking toward Garrett's hand.
2:41 - Persson moves his lips as though he is saying something silently.
3:32 - Persson scrunches his mouth to his left and shakes his head
3:41 - Persson does the same motion but more subtly
3:46 - Robbi scratches her face whilst announcing it verbally. Potential signalling to Perrson.
3:57 - Robbi looks toward Persson and makes a very small pinch of the lips on her right of her face.
4:52 - Robbi puts out a time chip, and looks in Persson's direction for a good 1s.
5:40 - Robbi looks in Persson's direction for another good 5s.
5:43 - In response to Robbi asking Garrett if he wants her to call, Persson says "I vote no". Robbi blinks as if in acknowlegement, and Robbi calls soon after.
9:24-10:36 - Persson has his hands in the steeple position, and looks nervous, swallowing. He rubs his fingers against each other and against his cheek. Why would he be nervous?
9:40 - As Robbie tries to justify her play, Persson interjects with "yeah, explain".
11:02 - Persson says that "Robbi did that for Andy", but when Andy distances himself from the hand, Persson quickly loses his smile.
12:59 - The next hand, as Garrett goes to peel his cards, Persson quickly looks left for his drink, and drinks whilst looking towards Garrett's hand...
Motivation
Probably Persson, Robbie, and likely also Rip wanting to humiliate Garrett because they can't beat him straight up as recs.
Thoughts?
