Ok, Bob, I understand your questions.
Once we started talking I did think of you as a good ally and friend, but knowing that a big alliance was together during the merge, as much as I liked you, i didn't want to give the alliance more power by being a mere pawn for them! I didn't come here to do nobody's dirty work! Even if I didn't have control over the majority alliance and my vote was pitiful each round, I came out as unthreatening to them and that's why I wasn't given a vote, but I didn't give them more power because that's not how I came to play the game and because I didn't want to ride coattails.
Regarding my game I won challenges when it was necessary and that led me to TWO immunity idols. I didn't rely just on my physical game, I did use my social skills and my strategic aspect to make those connections that made Robby target you, that got him out during F4 and that made me be the last person to ever receive a vote against them. The only reason why I depended a lot on winning challenges was because with the majority alliance shifting gears after you were voted out, I couldn't control them anymore and it came down to me facing the odds to get to the end. That was the point when immunity and idols became fundamental and were a huge reason of why I didn't need an alliance to make it to the end!
Hope you can see the different facets that made my game and give me a fair chance to win the game. Hope that answers your question, Bob. GG!
