The two also observe the judge of the competition, Riku, a horticulturist who has done landscapes for many stars.
Marilyn tells the society members that they are going to lose the Southeast Michigan Gardening Cup because their competitor has ghost orchids. This makes the members nervous.
On the day of the examination of the garden, the society members show up in their best spirits, only to be surprised by the Maoi statues that Marilyn has gotten placed in the garden to increase their chances of winning.
Catherine disagrees with Marilyn regarding the Eastern Island statues, but cannot override her decision because Marilyn is the president of the club. Moments later, judge Riku arrives to examine the garden. He appears mostly impressed by it, which makes the members hopeful about winning.
Unfortunately, the winner is announced to be the Bloomfield Hills Garden Guild, which has won the competition for a second year. At the next gardening session, Catherine tells everyone that they lost because of their poor marks in cultural appropriation. Then, she is unanimously voted in as the new president of the club.

When Catherine goes to deliver this news to Marilyn, she sees how sad her personal life is and decides to give her another chance. Later, Birdie sees Riku and Theodore in an intimate setting at a bar and informs other society members.

Based on ethics violations, Bloomfield Hills gets disqualified. Marilyn shows the cup to everyone at the garden society in the next session. She even gets Catherine's support, which suggests that they finally might put away their differences.
