Tonight they taped the show that will be aired tomorrow.
Hayden did not use the Power of Veto and Britney was evicted by Enzo - the only person to vote.
The final endurance competition, part one of a three part final HoH competition, started as the taping ended. The competition had the three guys sitting on swings and banging into walls on both sides as they swing back and forth. The competition sounds very similar to an endurance competition from last season where the HGs were repeatedly swung into a wall. The difference being they are hitting a wall in both directions this time.
We won't find out who has won the competition most likely until after the show airs Wednesday night and the feeds return - the actual ending won't be shown until Thursday's show - but by then we should have been able to deduce who won part one by the HGs discussions in the house.
