There is one argument that could be used to get Eric to give up the necklace in favor of the HII and it is this: If Eric gives up the IN to someone and makes himself the target, the person making the argument can point out that Eric by having the HII could control who goes home (Just like Amanda and Pavarti did last week). This would be a big incentive to Eric if he believed he could essentially control who was going home. Just a thought.
