Parsley/History

In the first episode, Parsley repairs Rosemary's locket.

In the second episode it is revealed that Parsley and Thyme are roommates, though Parsley is unaware of Thyme's hatred of Rosemary and assumes they are all friends.

In the third episode, Parsley excels at her smithing class, so much that her instructor, Professor Pluck, promotes her to a higher class. He also tasks her with a special exam, but it results in a Travern infestation.

In the fourth episode, Parsley, like the rest of the academy students, is sent home for the weekend due to the school suffering from a travern infestation. Parsley asks Thyme why she isn't going home to her family, and Thyme says her mom is out of town, so Parsley invites her to dinner with hers. It is later revealed she is lying - Thyme's mother comes to pay a visit to Parsley's mother, as the two are close friends, and the latter invites her to stay. Throughout the dinner, Thyme and her mother make subtle jabs at each other.

Even though Parsley's parents initially seem to be supportive of her career as a blacksmith at school, they eventually admit that they were hoping that Parsley would drop out because they have recently had their 15th child and need an extra hand. This causes Parsley to have a mental breakdown and admit that she felt like she didn't get to have a normal childhood because she had to raise her siblings, being the oldest and a girl, and she carries a lot of mental scars from her parents' parentification. She then yells at her parents that since they have a new girl, they can raise her to be the help, causing them to gasp. Thyme interrupts their conversation by alerting Parsley that one of her brothers is on the roof. The two use their skills to successfully bring him down without hurting him. Near the end of the episode, Parsley's parents apologize for their lack of care towards her as a child. Thyme's mother also apologizes to Thyme for her neglect.

In Episode 5, Rose and Parsley are partnered with Snapdragon as part of a project. Parsley does most of the work expecting to be praised but Snapdragon still criticizes her attitude a subpar work. He also insults them both, which culminates in Rose challenging him to an arm wrestling match, which she wins. Later Thyme tells them she accidentally insulted Sage and made her cry, and can't find her.

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. This prompts Snap to ask "since when are you two all chummy" and she replies that she could ask the same to him, to which he explains that they are doing a project.

Meanwhile Sage also practices her magic, but accidentally duplicates Parnelle's groags and traps Slime Boy and Parnelle in bubbles with them. Rose, Snap and Parsley find her, and try to help diffuse the situation. In the end, Sage finds a way to undo the spell, and Thyme apologizes for making her cry.

In Episode 6, Parsley is partnered with Parnelle. She quickly finds that Parnelle is rather skilled at athleticism, and she follows his example in the final obstacle course. When she is awarded as the best player, she tells the teacher that Parnelle deserves it, only to be told that it is because she hammered through the most obstacles. He also says that he will only dock off points if she caused grievous bodily harm to someone, so she crushes Aster's foot with her hammer to the approval of their teacher.

In Episode 7, the four fight off a dragon while in the cave of Vinca, and Parsley is horrified when Rosemary is injured to the point she dies. They manage to heal her with the water and near the end, Parsley and their friends witness Thyme heal the tree.

In Episode 8, she cosplays as her smithing teacher for the Festival of Fall. Later, 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. Thyme is also horrified to see that her best friend (Parsley) is one of the victims of the spell. She helps Rose and Sage hunt her down to reverse it.

In Episode 9, Rose and Olive have a huge fight which culminates in Olive being gravely injured to the point she starts to bleeding to death. After her last offer to go with her to meet the Triumvirate was rejected, she released some light to blind the guardians and escaped. Sage managed to undo the spell by smashing her terrasphere. Parsley was turned to stone and was about to fall, but as she turns back, Neppy cat catches her.

Later when Rose asks Sage if she wants to hang out, Sage rejects her in favor of Snapdragon.

In Episode 10, Parsley follows Thyme to her journey to summon a demon so she can inform her father about the healing waters, and the two fight off monsters together, while Rose narrates spooky stories to her friends.

In Episode 11, Rose and her friends are selected to aid the Merpeople into capturing a sea dragon. Unfortunately, Sage panics when witnessing the excessively violent behavior of the creature and accidentally kills it. However Parsley comforts her.

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.

When the school's loudspeakers announce that all students are mandated to go the forge for an assembly, Rose, Sage, Parsley and Thyme don't listen to it, due to witnessing Carsway's imposter prior and fearing that it could be a ruse. Their fears proven correct, but the four manage to fight off Olive and Mandrake, meanwhile Amaryllis and Snapdragon try to rescue the remaining students. In the end, Olive betrays Mandrake and stabs him. Hours later the fire is put out and the teachers are cured, but Olive is seen being arrested.

At the end of the episode it is revealed that Lavender is alive and has been working for the triumvirate. She berates Mandrake for failing to kill the students of High Guardian Academy. He begs her to have mercy on him but she refuses, and kills him.
