The honor goes to queen Casey from The RW/RR Challenge
She will ~always~ be the queen fresh meat. Upon first sight, she seemed totally useless, but in reality she was only a little bit useless ^_^ i was 9 when i watched this on tv, i probably should not have been even watching this show at that time, but i loved it. My second season the the challenge that i watched on air, wes and casey had me rooting for them from the very start. Surviving 5 out of the 7 exiles, it was the first case of bottomgoddessing i was really ever exposed to and i absolutely loved. From then on, i almost always root for fierce underdogs, and Casey is to be thanked.
However, Casey herself was totally fierce. I laughed every time when she bitched at Wes for calling her a bitch and other derogatory terms in the exiles < 3 i loved when wes and casey were in exiles and the horn blew, and they picked up their bags like nothing and the competing teams would be so overwhelmed at their weights and struggling at the start < 3 Then she randomly came back in the ruins and floated to the final elimination l0l. What a queen < 333
