I'm trying to get a read on Dawn's expressions through the sequence. She seems to start out as something close to darkly bemused, while the lower photos -- well, it's possible for to see her as almost supportive of Brandon in those still shots (although there might be a bit of 'Come and get him. Yes, him. The yutz with the tattoos.'). I'm not sure the end pictures come from after the incident. Contrast this to Brenda (terrified) and Andrea (rubberneck shaken), which might have been captured while it was happening.

Note the position of Brandon's arms during the rice dump and the gradual increase in the container's tilt: he starts out hugging it to his body as if lifting a great weight, then gradually extends and lowers one end as the mass drops. Towards the end, there's a good chance he's gotten rid of just about all of it. If he's holding the bean container when Erik approaches, then he has gotten all of them -- it's upside-down and there's no visible sign of content fall, plus Brandon doesn't seem to be putting much effort into lifting it. I can't see if it's open, though -- lid or plug? No idea what the hanging bag is, or was.

(It's not pictured, but I'm wondering if he'd go after the other Reward items -- really take out any gains the tribe had made. Some things are more crucial than others.)

Erik's actions are rulebook-savvy here: he seems to be trying to stop Brandon with as little contact as possible, which could put Erik out of the game. If Brandon was being protected on a scale equal to one RussHell...

...disturbing thought, but I suspect the show may have finally had enough of this family. Or at least the males.
