The weekly food competition that normally takes place around 10:00 am BB time Thursday is starting just after 8:30 pm BB time Thursday night...it's the Clambake from Hell.

The weekly nomination ceremony will definitely not be held until Friday. That means the veto competition probably won't take place until Saturday, but that is still unclear at the time of this posting.

The veto competition is scheduled for Friday evening. As of 4:45 pm BB time Friday, the HGs are on lockdown in preparation for the competition.

An announcement was just played to the HGs that the veto competition will begin in two hours--around 8:15 pm BB time Friday evening.

I wonder if it involves lasers similar to the POV comp that Marcellas won last year.

Very possible--it's at least something that the producers held until nightfall before starting. The competition is definitely an individual challenge and not an elimination like the last couple have been.
