Yeah it was Randi. I just looked up and the episode summary on wiki
* Yellow District - Zach (5) defeated Taylor (4)
As there are 5 girls in the yellow district, Taylor was confident that she had all their votes. It turned out Zach was able to persuade Randi to vote for him by suggesting that it might be best for everyone if someone else had a turn at being council leader.
And thanks. I've actually been here a few years, but I lurk without signing in lol I'm pretty sure I posted years ago but I guess those posts and forums are lonnnnng gone now.
