Well, they did quit once and have threatened to quit a few times since.
Lucy & Emilia were 10x better since they actually wanted to be on the Race. It's like these last few legs RR & Jeck would much rather be eliminated, but until they run out of luck, they don't mind the TV exposure. There's a difference between weak and completely checked out of the Race and walang pakialam, so to speak.
The only other awful team for me are Vince & Ed. I hope them and RR & Jeck are the next two eliminated because everyone else is fine, have forgotten stupid alliances and are finally racing.
