After watching the latest episode of Blood vs Water I had a question about the rules. I was hoping one of you awesome people could clear it up for me.

After having a tie vote twice they get one last chance to come to a unanimous decision before they have to draw rocks. My question is, who gets a say in that unanimous decision? Is it all four of them that voted or just the three that would have to draw rocks. Basically, did Gervase have a say?

Hypothetical situation time. Say Tyson had agreed to vote out Monica to avoid drawing rocks. Could Gervase disagree and make them draw rocks anyways since it had to be unanimous? He had immunity so he wouldn't have had to draw. From his perspective, rather than guaranteeing his ally Monica being sent to Redemption Island, forcing the other three to draw rocks gives him a 2/3 chance that Katie or Ciera went out and only a 1/3 chance that it was his ally Tyson.

To me it doesn't seem fair for him to have that much power but I don't know. Thanks for any input you may have.
