Pretty dull episode, especially for a season premiere. Not every episode can have large wheels of cheese rolling down hills, but still.
If Ethan and Jenna wanted to go unnoticed, I'm surprised that they didn't take more steps to alter their appearance, particularly since they were going on a reality show amongst other contestants who presumably are reality show enthusiasts and would likely know them. He could have shaved his head, she could have dyed her hair, or something similar. Assuming they could get through under the radar like that was a fatally flawed strategy.
Did the passport story make news when it first happened (if not in mainstream outlets, then in forums or reality blogs)? If not, I don't believe it for a second.
And finally, I can't believe it took that many teams so long to correctly recite the Confucius proverb.
