She then begins bawling to her cousins, and then apologizes because she hates yelling.

As they walk in the halls looking for Sage, Amaryllis asks him what he's doing with Rose and Parsley, but when she notices Thyme, and she starts acting friendly with her.

Rosemary quickly becomes smitten with the latter due to his good looks, fighting skills, and accomplishments. Throughout the obstacle course, she acts extremely love struck over him, not even correcting him when he accidentally calls her Rhubarb instead of her name. But she eventually realizes that Aster, in actuality, is quite weak and shallow, and becomes tired of his constant bragging of his achievements and narcissism.

Later Rosemary and Sage have a disagreement because the former put all of her friend's names for the flaming axe challenge, even though Sage wanted to compete in the gourd carving competition. She then confronted Rose's pushy behavior, saying that they always had to do what she wanted and it wasn't fair to make her miss something she was looking forward to for along time. Rose then called Sage's interests boring, which caused Sage to walk off.

Neppy cat alerts Thyme of Olive. Olive steals Thyme's healing water, and tells the guardians that she wants them to come with her to the Triumvirate. When her offer is rejected, she smashes the vial. She then tries to attack the guardians with a spell, which results in the festival goers turning to stone because of Parsley's blacksmithing magic clashing with said spell. Sage, Rose and Thyme hunt her down to reverse it.

The four eat seaweed that turns them into mermaids, but then the Scypith attempts to attack them. Elodie appears and uses herself as a diversion, explaining that he primarily targets normal mermaids like her. Later Elodie invites them to her sea colossuem, and explains that as a baby, the Scypith was formerly a friend of theirs, but as he grew up, turned evil. She also introduces herself and her friends, Coral and C. Elodie and Rosemary also bond over her pet seahorse, but their fun is cut when the Scypith tries to attack them again. The mermaids then try to form a plan where they can trap the Scypeth and use the horn of the seahorse to turn it back into its normal form.

Unfortunately, Sage panics when witnessing the excessively violent behavior of the creature and her terrasphere goes out of control, and ends up accidentally kills it. She cries, but Elodie tells her she knows it's an accident. Caraway and Redbud also assure her that she is not at fault.

In Episode 12, Mandrake shapeshifts into Lavender, and tries to get information out of Rose about the whereabouts of herself and her friends. Though she instructs Rose not to tell anyone else of her presence, but Rose, unable to contain her excitement, tells her friends and they decided to tell Caraway as well. They enter Caraway's office and start telling him about Lavender, but the real Caraway walks into the office and is confused to see a doppelganger, causing the two to have a fight. Olive and Mandrake attack the school by having the latter impersonate Professor Caraway, lead the teachers into a room, trick them into drinking poison and locking the door so they can't escape. They also set the school on fire and bar the students from exiting the building.
