"Olivia! Call me Olivia, please. 'Professor Green' makes me sound like an ancient crone."
— Olivia Green to Jacob's sibling[src]

Professor Olivia Mehira Green[9] was a witch who attended Hogwarts School of Witchcraft and Wizardry in the second half of the 20th century and was sorted into Ravenclaw. She was friends with Duncan Ashe and Jacob, who were in her year.[5] She later worked for the British Ministry of Magic as an Unspeakable in the Department of Mysteries, and eventually joined the Hogwarts faculty after graduation, becoming the school's Defence Against the Dark Arts teacher in the 1990–1991 school year.[4]

Biography[]

Hogwarts years (1974–1980)[]

Sir Nicholas: "She was a student in your brother's year. I remember her for her exemplary bravery."
Jacob's sibling: "Was she a Gryffindor?"
Sir Nicholas: "You would think so, but she was actually a Ravenclaw.... You should pay a visit to the Grey Lady..."
Nicholas de Mimsy-Porpington to Jacob's sibling[src]

Born into a family of unknown wizarding descent in the early 1960s, Olivia attended Hogwarts School of Witchcraft and Wizardry, where she was sorted into Ravenclaw House.[5] She was considered by many to be one of the brightest girls of her year, as some of her school comrades noticed how "wicked smart" she was. She got acquainted with Jacob, who were in the same year as her, during one of their Transfiguration classes, and the two became close friends.[3] They shared a common passion for the fabled Cursed Vaults, and decided to work together to uncover their secrets.[10][3] Olivia also became well-acquainted with Duncan Ashe and, according to Jacob, was in love with him.[3] She once got lost in a maze of books at Flourish and Blotts trying to get her school books.[11]

Olivia paralysed HM746

After Duncan started to brew an Erumpent Potion, Olivia, believing it was Jacob's idea, went to talk to him about it. She later spied on Patricia Rakepick and found out about her plan of using mind control, and that the potion was her orders. When Duncan died from brewing the potion, Olivia came to talk to Jacob again while sobbing, and went to confront Rakepick. She told her that she knew all about her plans, which made Rakepick cast the Full Body-Bind Curse on Olivia and wipe her memories.[12] This was likely why according to Jacob, she started acting strange following Ashe's death, as if "nothing happened", and abandoned the search for the Cursed Vaults. She eventually cut ties with Jacob to the point she did not write him after he was expelled in 1980.[3]

During the 1988–1989 school year, Jacob's sibling found a letter written to Olivia Green from Jacob in Jacob's room, where Nicholas de Mimsy-Porpington informed them about her, who, according to him, possessed exceptional courage. He then told them to seek the Grey Lady for more answers about her.[5]

Working for the Ministry (1981–1990)[]

Following her graduation from Hogwarts, Olivia joined the Ministry of Magic in London, where she worked in the Department of Mysteries as an Unspeakable.[7] The Archivist Elton Elderberry was a mentor to her at the Ministry.[13]

During her time as an Unspeakable, she appeared to have had a link to the Brain Room, given how she mentioned "thoughts" to Jacob's sibling whilst talking about her job.[7]

As the Defence Against the Dark Arts professor (1990–1991)[]

"All right, class, let's stop whispering about the new professor of Defence Against the Dark Arts... She's just arrived, and she might hear you! Allow me to present... me. Your new Defence Against the Dark Arts professor. Now some of you may be wondering if I'm 'secretly evil'... And I suppose that's why you're here. To learn how to defend yourself, in the case that I am. Some of you may have already heard that I was once a Hogwarts student, just like you. My Defence Against the Dark Arts experience was also a bit... uneven, should we say? But you have no reason to fear. I've had years of practice, and you're in capable hands... I hope, in time, we can all grow to be friends. To that end, none of you are allowed to call me 'Professor Green'! I forbid it! To my students, I am simply... Olivia."

Professor Green introducing herself to students in Classroom 3C

In the middle of the 1990–1991 school year, Green was contacted by her old school headmaster, Albus Dumbledore, who informed her that one of the staff had abandoned the post and left the school in the dead of night, thus leaving them in dire need of an emergency replacement for the position of Defence Against the Dark Arts teacher. Upon learning this, she resigned her position at the Ministry and agreed to return to the school as a teacher. When she introduced herself to seventh-years at the start of a lesson in Classroom 3C, she told them that she wanted to be addressed as "Olivia" rather than "Professor Green".[4]

Due to Lord Voldemort's jinx on the post, it was expected that Green needed to be replaced by the end of the school year.[14] Beforehand, Olivia tasked Jacob's sibling with investigating rumours about the jinx for her; they were unable to completely prove its existence, but nonetheless found that the rumour did persist throughout the school, and Green decided to be vigilant about it.[15]

Olivia Green speaking to McGonagall HM742

Green speaking with Professor McGonagall at Hogwarts

Green kept in her office a Nose-Biting Teacup, her journal that contained simply everyday notes along with a recipe for butter cookies, and unknowingly a chest of stored memories in phials kept hidden behind a painting of a lotus flower, marked with her initials. She often wrote in her journal in the Clock Tower Courtyard in her free time. At some point, she was found writing in the courtyard and having a friendly conversation with Professor McGonagall, a new colleague who she already seemed to be on good terms with. She told McGonagall she had only pleasant memories of her time at Hogwarts, which Jacob's sibling found odd, considering how her time at Hogwarts was affected by the Cursed Vaults. Green later returned to her office, which, unbeknownst to her, Jacob's sibling, Jae Kim and Nymphadora Tonks had searched.[16]

Olivia Green and Jacob's sibling HM743

Green with Jacob's sibling in the Clock Tower Courtyard

When Jacob's sibling was gathering their thoughts in the Clock Tower Courtyard, Green interrupted and joined them, where she spoke to them about their brother Jacob. She cryptically told them about her past employment as an Unspeakable. During this conversation, Green seemed to incorrectly remember Duncan Ashe's death as having been caused by the Draught of Living Death that he had taken on a dare, but Jacob's sibling knew it to be an accident that occurred during the brewing process of an experimental Erumpent Potion he had been coerced into making by R. After Green left, Jacob's sibling decided that her faulty memories needed fixing.[7]

Students leaving the Headmaster's office HM744

Green and the students in the Headmaster's office

Green's office was broken into again by Jacob's sibling and their accomplices, after they had released Tim the Wampus cat into the Clock Tower Courtyard as a major distraction. Green subdued Tim with the Sleeping Charm and had Professor Kettleburn return him to the Care of Magical Creatures reserve, and then angrily caught the students in her office in the act. She questioned them and was accused of having faulty memories by Jacob's sibling, to which she denied, and was stumped to know she possibly had her memories kept secretly in the room. She escorted them all to Dumbledore in his office, where she told the Headmaster about their rule-breaking. After the Headmaster decided not to expel them, he told Green that she could view her memories in his Pensieve if she wanted.[17]

Green then spoke with Jacob's sibling in her classroom, where she told them she planned to view her extracted memories in good time, as she had come to the conclusion that her memories had been tampered with. She also asked them if they knew how memories could be altered, including the implanting of false memories in the mind.[17]

Olivia Green and Pensieve HM746

Jacob's sibling and Green finishing viewing the memories

When Green was ready to view the memories, she summoned Jacob's sibling to do it together, and witnessed the memories that Patricia Rakepick had taken from her. She thought about exiting several times, but went through with it, and after finishing, she left without saying a word. Jacob's sibling later found her in her office and talked with her about the memories. She revealed to them the mind control plan that she had overheard Rakepick discussing, and they also talked about the identity of the student's father, Peregrine, the leader of R.[12]

One morning following R's defeat and the dissolution of the Circle of Khanna, Green resigned from her post without a word and left for the Ministry. By the end of the day, she was already replaced by Quirinus Quirrell, who just returned from his sabbatical in Albania.[18]

Relationships[]

Jacob[]

Olivia was friends with Jacob at Hogwarts and helped him search for the Cursed Vaults, but stopped communicating with him after he got expelled.[3] After his release from St Mungo's, Jacob would start living with Olivia, where he would eventually develop feelings for her.[20]

Duncan Ashe[]

Green was supposedly in love with Duncan Ashe while they were both at Hogwarts, and was said to have acted strangely after his death.[3]

Jacob's sibling[]

Green developed a friendly and informal relationship with Jacob's sibling when she started teaching. She requested them not to formally address her as "Professor Green", but just "Olivia".[7] However, Green was angered and upset when she discovered that the student had broken into her office to search it, although she forgave them afterwards.[17]
