Ma, who was eliminated after becoming surplus to requirements in her Upolu alliance, said the only reason Hantz was still there was because he had been taken under the wing of Upolu's leader, Benjamin "Coach" Wade.
"For some reason, Coach saw a lot of the way Brandon behaved as how he played the game the first time he played. He felt very protective and fatherly towards him."
Ma, a 35-year-old anesthesiologist from Los Angeles, said her mistake was failing to become part of a solid alliance from day one.
"Upolu was trying to maintain their original core five from the alliance they formed on the beach on day one. I was annexed from that tribe, I wasn't an equal team member," she said.
"There were promises made but you can't believe anything that you hear. Their line of reasoning baffled me so I didn't really take much of it into consideration. Coach didn't object to it, he did vote for me in that manner I guess he's endorsing me being voted out."
Being told she wasn't an equal team member was the hardest part of being on Survivor.
"In day to day life I have people's lives literally in my hands. Being out there and being told to sit out challenges and to be told I wasn't an equal member of the team, that was the hardest part for me - the lack of respect people had for one another."
