I'm not able to live blog tonight, and we learned the perfect matches last week, so this post is open for comments!
Something that came up in the comments last week was the likelihood that the house figures it out. My thoughts:
When the house comes up with a combination, they are able to evaluate whether or not it is a possible winning combination. With 22 people, remembering that information shouldn't be so hard. We now know that there is only one possible winning combination left. So if the house is able to try combinations until they come up with one that matches all of the ceremonies and truth booths, that means they found the winning combination.
By comparison, in seasons 3 and 5, the house went into the final matchup ceremony with multiple possible winning combinations. That meant they could do their best to come up with a possible winning combination, which both seasons did, and still lose. Season 3 certainly beat the odds in that regard.
Terrence J did confirm that this season's house has the fewest perfect matches (0) to this point and a very low number of beams for matchup ceremony 8, but as we saw, they actually got it down to one possible winning combination quicker than some of the previous seasons, some of which only had 10 couples.
