After her return, she comes off as slightly rude and is attempting to transfer to Princeton University. In Season 3, she is seen as still following Laura's vlogs, and helps the group decipher some hieroglyphics written in a dead language.

She later reappeared, but couldn't remember what happened to her and eventually turned into a party animal.

J.P. Armitage (played by Dillon Taylor/Aaron Chartrand) is a student of Silas from the 1800s who was sucked into the computer system. J.P. originally resided in the library, but was transferred onto a flash drive by LaFontaine and is brought back to Laura's room. He aids Laura and her friends when they are researching information in order to find out how to stop the Dean's evil plan. His flash drive is destroyed by Carmilla's mother, The Dean, but later it is revealed that LaFontaine made a backup of J.P. on another flash drive. Laura mentions that she thinks LaFontaine and J.P. are dating at the end of season one, but this has yet to be confirmed by either of them. During the second season, the library disappears due to Matska taking charge at Silas and so does much of J.P. with it, until LaFontaine manages to bring him to life in Will's body after finding it on a trip to visit the Lustig crater. Due to the fact that the body J.P. inhabited is that of a vampire, he now possesses the same traits and abilities as the aforementioned supernatural. In Season 3, he is retained against his will by the Dean.
Theodore "Theo" Straka (played by Shannon Kook) is a member of the Zeta Omega Mu fraternity and is introduced in the second season.

In Season 3, he joins the Corporation and starts working for the Dean.
Melanippe "Mel" Callis (played by Nicole Stamp) is a member of the Summer Society and is introduced in the second season. In the second season, she is shown to be ambitious, fierce, loyal to her Summer Society sisters, brave, arrogant, and doesn't get along with Danny or the Zetas. Mel strives to claim the title of the president of the Summer Society the following year from Danny assuming her budding friendship with the Zetas and interactions with Laura and Carmilla will end up in her demotion once and for all. When Mel plans to kill Kirsch in the Adonis Hunt, Danny stops her, this allows Mel to win the election to become the president of the Summer Society, despite this she still takes orders from Danny who is the Student Representative of the Board of Silas. In Season Zero, set in 2012, Mel is shown to be shy and nerdy, wearing glasses and conservative clothing. In Season 3, she is trapped underground working for the Dean, and videoblogs her experience, in hopes of the troupe finding and rescuing her.
Matska "Mattie" Belmonde (played by Sophia Walker) is the Chair of the Silas Board of Governors and was also resurrected by the Dean, making her Carmilla's older vampire sister. Her relationship with Carmilla is different than her mother and other siblings, where it shows the two have a great friendship and have had each other's backs for over 300 years. Despite this, Mattie often chides Carmilla over her relationship with Laura. When she loses her power as the Chair of the Silas Board to Vordenberg, she becomes a fugitive when Vordenberg orders the detainment of all known vampires. She is eventually killed by Danny, who only got the information to kill her from Laura who gained the information from Carmilla. Her death also sets Carmilla against Laura and the others. She is later revealed to be alive. In season three it is revealed that Mattie now has to work for a death goddess named Ereshkigal.
Cornelius Hans Albrecht, Lugenbaron von Vordenberg (played by Ian D. Clark) was a member of the Silas Board of Governors.

However, after a heart to heart talk that begins by him confronting her, Mr. Hollis comes to accept the vampire, even going as far as having a friendly discussion with her in which he narrates embarrassing stories of baby Laura. From then on, he starts helping the group.
Elle Sheridan (played by Dominique Provost-Chalkley) was the former lover of Carmilla Karnstein. Living in the mid-1800s in a Victorian manor, Elle fell in love with the girl her family had taken in, Carmilla Karnstein. After Carmilla's mother (who is revealed to be Lilita Morgan in the web series) reveals to Elle that Carmilla is a vampire, Elle becomes horrified and tricks Carmilla into revealing her true self to her. Elle leaves with Carmilla's mother, and from there is sacrificed to the angler fish god. Elle has been revealed by Steph Ouaknine to be the Laura in the original novel by J. Sheridan Le Fanu, who inspired the character's last name in the movie. She is the antagonist of the movie.

She works with Elle Sheridan in hopes that she will finally pass, but is tricked by her. At the end of the movie, she is able to finally pass.
Charlotte Brontë (played by Grace Lynn Kung) was the sister of Emily Brontë, a victim of Carmilla Karnstein. She is also stuck in the ghost state that Carmilla's former victims were, despite not being a direct victim of the vampire. It is revealed in the movie that she was stuck in the same fate as her sister, as she died trying to save her. Charlotte, based on the poet of the same name, appears to be the less welcoming of the two Brontë sisters. She seems to be emotionless, until she forms a romantic bond with Mel. At the end of the movie, she is finally able to escape the 'nightmare land' she and the other ghosts were trapped in, and finally pass in peace.
