If Gaia preferred Olivia to just let nature take care of the flowers, why didn't she mind a greenhouse or Nick making a temperature regulating machine? Aren't those also manmade? XD
I look at the unrevealed leader silhouettes to try and guess their types, and I assumed this one was Psychic because of the hair (it kind of looked like the top right bit was floating or some kind of residual energy, but now I see that's part of the leader sprite to the right of her). So I was wrong for this one.
