|I think what's confusing you there is that Matt has an N on him for Nominated and Natalie has a V for POV, implying that those letters only apply to those individuals. The letters apply to the whole couple, they just put one on one end and one on the other. The other nominated couple is Ryan and Allison (even though the N is on Ryan).|
What may also be confusing is how Jacob is X'd (evicted) and his partner Sharon has an H for HOH. Jacob and Sharon were evicted as a couple. Then Joshuah's partner Neil had to leave the house for some family problem. They brought back Sharon as Joshuah's new partner, and they are the HOH couple this week.
