I think the third answer should not be counted as correct mswood, that would be unfair for people who actually picked the correct person. Just my 2 cents worth. If people want to pick the third option, they mind as well try their luck with either of the first 2 options?
My questions unless specifically included in the question (like the question on Peach's score) should always have an answer thats provided by the episodes themselves.
Herb and Nate are not referred to by name so far this season, thus why I included the 3 option. As I don't require fans to know materials that are from outside sources unless specifically addressed in the body of the question itself.
Now Jet & Cord or Jaime & Cara are of course referred to in the episodes and credits, so people have the opportunity in the episode to know who is who.
It is basically designed as the Bonus question this week.
