As reported in the last post, the second part of the final HoH competition was held last night and won by Porsche. From the few details we have been able to glean from the talk afterwards, sounds like they were underwarer for a lot of it. It is possible that the competition was similar to the one shown below from Season 8.
After the competition Porsche and Rachel said they would take each other to the finals no matter who wins Wednesday's Part 3. Rachel then actually told Adam about the deal at about 9:39pm.
There is no TV show tonight as CBS will be running 9/11 programming.
