You're the one who made the claim that the "body language [sic] so off" off of one photo, I didn't make a determination either way, because again, it's one photo.
In the very next moment, all three could've been laughing together.
I then made it a point that if you were such an expert on body language, you would know from looking at that snapshot that it could be perceived as them building rapport with one another as that's what mirroring, subconsciously, does. But you chose to see that picture in the worst light possible, for whatever reason, most likely because you already have a preconceived notion that this playing group is doomed from the get-go.
