1) Who is the most annoying person left in the game and why?
I have to say, the most annoying person left in the game is definitely Bella. I haven't gotten to know some of the quieter people too well, but Bella definitely isn't quiet, and that's mainly why she is annoying. She spends a lot of time thinking she is dictating all the proceedings, and just telling people what they HAVE to do, and trying to be immensely important, and while she may be significant, her annoyance level in no way is merited.
2) Which person remaining would you say has the WORST personality and why?
Bella probably has the worst personality because she is very demanding, and attempts to cause drama and do things that are just not needed. I believe she has good qualities in that she has ambition, and is determined to win, but she has some cocky tendancies and doesn't care about how her actions make others feel, and those aren't admirable traits.
3) Who didn't deserve to leave the game before merge and why?
Definitely Lafayette. Due to the no intertribal communications rule, Lafayette was completely out of control of who was sent to exile on her side, and the fact that she was the only person without idols, is just a crappy way to go, especially after surviving a tribal that someone who later ended up getting back into the game was voted out of.
