While I'm certainly not sharing any tears over Bobby being gone, that tribe just lost a major contributer in the challenges, IMO. Were it not for him, I have a feeling a lot of fish would still have their heads. Which reminds me, what a less than ideal way to be introduced into sushi.
If it were me, I would have kept Bobby around for his strength for a little while, knowing that at some point, he was a goner. I would have dropped yoga girl.
As far as the other tribe, who knew the damage that some beans could inflict?
