Lily Sunder

Lily Sunder is a professor of apocalyptic literature who fell in love with an angel only to have him and her daughter murdered.

Background
In the late 19th to early 20th century, Lily was a professor of apocalyptic lore with a daughter named May and studied angels heavily, eventually becoming fluent in Enochian. Lily's studies led her to a spell that enabled her to summon an angel and when she cast it, Ishim appeared. Ishim grew obsessed with Lily, believing he was in love with her. As a result, Ishim shared all of the secrets of angels with Lily. However, Lily came to realize that Ishim was a monster obsessed with her. Following her realization, Lily cut off contact with Ishim, eventually meeting, and marrying the angel Akobel so that he could protect her from Ishim. Upon learning of this, an enraged and jealous Ishim set out for revenge. To do this, Ishim gathered his flight, including Benjamin, Mirabel and Castiel and claimed to them that May was a Nephilim and she and Akobel needed to be killed. When the angels arrived, Akobel ordered Lily to take May and run while he distracted them. As Lily desperately gathered her things, Akobel was killed by Mirabel and Ishim entered the house to confront her. Pinning a powerless Lily with telekinesis, Ishim accused her of leaving him for Akobel and murders May in revenge. Ishim then leaves Lily to mourn May's loss.

Over the next century, Lily began using her study of Enochian magic to give her immortality and the powers she would need to get revenge on Ishim and his flight. Using Enochian magic in such a way burned away a piece of Lily's soul each time, eventually resulting in her losing the ability to dream. Despite this, Lily pressed on, consumed by her revenge.

Following the Fall of the Angels, Lily finally saw her chance for revenge and took it. Lily was able to kill two of Ishim's flight with her new abilities and gain their angel blades for her own use.

2017
Lily eventually tracks down the angel Benjamin as he plays arcade games and confronts him. Lily battles Benjamin who proves to be no match for her and eventually pins the angel up against a wall. After Benjamin begs for help over "angel radio", Lily kills him with an angel blade.

Next, Lily goes after Mirabel, Ishim and Castiel as they meet in a diner to discuss the situation, being the last three angels alive that Lily is hunting. As Mirabel checks the perimeter, Lily ambushes her and quickly kills the angel. Ishim eventually emerges looking for Mirabel and is shocked to find Lily who slashes his side with an angel blade. Ishim attempts to smite Lily, but her new powers render her immune to Ishim's smiting. As Lily gains the upper hand against Ishim, Castiel arrives and slashes her with an angel blade, also recognizing her from the murder of Akobel. When the Winchesters arrive and point guns at her, Lily tries to convince them to allow her to get her revenge, not wanting to hurt humans. When they refuse, Lily lets off a massive blast of light that blinds everyone and flees in her rental car.

Returning to her hotel room, Lily heals her wound and later departs to find Castiel and Ishim to get her revenge. To her surprise, she is confronted by the Winchesters who had managed to track her rental car after Sam saw the license plate during her escape. When the Winchesters attempt to talk her down as they believe her daughter was a Nephilim, Lily tells them the truth about what happened the day Akobel and May were murdered, breaking into tears. Inclined to believe Lily but needing proof, Dean heads off to confront Ishim while Sam stays with Lily. Lily explains to Sam the source of her powers and why she had waited so long for revenge then tells him that after Ishim kills Dean, Sam will help her so she is willing to be patient further. Concerned by her words, Sam agrees to take Lily to confront Ishim. Arriving at Ishim's church safe house, the two find Castiel nearly unconscious and Dean cornered by the rogue angel. Armed with an angel blade, Lily engages Ishim in battle with the two hunters attempting to aid her without success. Having been fully healed by Castiel, Ishim proves to be more than a match for Lily who telekinetically flings him against a wall. However, Ishim tells her that she can't hold him there forever and begins to fight through Lily's hold, slowly advancing on her. As the Winchesters and Lily helplessly watch, Ishim eventually reaches her and prepares to kill Lily with his angel blade. To everyone's shock, at the last moment, Castiel kills Ishim from behind with an angel blade of his own. As Lily stares at him in shock, Castiel tells her that "you held him for long enough".

Following Ishim's death, Lily stares down at his body and the imprint of his broken wings. The Winchesters question whether or not Lily will give up on her revenge now that Ishim is dead, but Lily isn't sure as revenge is all she's had for over a century. Now knowing the truth about what happened in 1901, Castiel apologizes for his role in the murders of Akobel and May and offers that if Lily leaves and finds that she can't forgive him, she can return to get her revenge. In tears, Lily thanks Castiel and leaves.

Personality
Lily was once a smart and kind woman who cared for her daughter very deeply. Her studies in angels however led her to meet Ishim, an obsessive and wrathful angel who desired Lily for himself. Lily attempted to flee from Ishim and form a new happy life with another angel, Akobel. This peaceful life brought on jealousy from Ishim, who arranged the deaths of both Akobel and May as punishment towards Lily.

From that point on, Lily herself began to change, becoming vengeful and willing to sacrifice her own existence in order to get back at the flight of angels who took part in the murders of her loved ones. Lily's use in Enochian magic gradually ate away at her soul, turning her into a dreamless and murderous individual who only saw revenge as a goal. After the death of Ishim, Lily admitted she wasn't sure she could give up on her revenge as it had been all she had for so long. in spite of the fact that the last angel she was after, Castiel, saved her life, she still wasn't sure if she could forgive him. After Castiel's apology and offer to allow her to return for her revenge against him at a later date if she wanted, she appeared to finally let go of her hatred and vengeance and move on with her life, tearfully thanking Castiel.

In order to enact her revenge, Lily developed a great deal of patience for it took many years before she could get her hands on her desired targets. Despite the increasingly loss of emotion, Lily still remembered her daughter and Akobel fondly, and could still feel sorrow by the time she encountered Ishim again. With Ishim's death, Lily was left to accept that her journey was over. It is unknown if Lily has managed to live a normal life or not.

Trivia

 * Lily is the human with the most angel kills in the series, having killed two unnamed angels, Benjamin and Mirabel. Dean Winchester has the second most having killed Zachariah and the Rogue Angel while a few other people have killed a single angel.
 * Lily is the first human to knowingly marry an angel.
 * Lily's gradual loss of her soul (and thus, her emotions) resembles Sam during his soulless period. Sam without his soul did not require sleep, let alone dream, and he cared little for the well being of others. Lily's casual remark of Sam losing his brother to Ishim is proof that Lily was becoming more like Soulless Sam.
 * Lily shares some similarities with Luther Shrike: both lost a child as a result of the actions of a supernatural being, both wanted revenge, both initially appeared to be the bad guy in their respective episodes but are revealed to ultimately be the good guy and both got their revenge through the actions of a third party. Unlike Luther, Lily lived to see her revenge exacted.
