Bob is the one person who gains from his fake HII. He not only gets Randy to put a target on himself but he makes a connection with Sugar as seen in the previews. Sugar is not totally comfortable with Kenny/Crystal but seems tight with Matty and appears to trust him. I see Sugar as seeing in Bob (and vice-versa) a potential alliance with someone she at least trusts.

I can actually see Sugar/Matty/Bob teaming up and ending up as being the perceived "good" (which from interviews and comments we know that is not necessarily true of Sugar, but after JP's comments about Matty being too honest and the comments JP made about underestimating Bob it wouldn't surprise me a bit) Corrine will end up hooking up with Kenny and Crystal (after jettisoning Susie) as will be perceived as the "evil." I'm not saying this happens but stranger things have happened on Survivor.
