Teen Wolf still lives on as one of MTV's most popular shows, as it created a cast of beloved characters that made fans laugh, swoon and ultimately reach for the tissue box. One of the show's most heartbreaking character departures was the tragic death of Beacon Hill's resident archery-enthusiast, Allison Argent.

Played by actress Crystal Reed, who left Teen Wolf at the end of Season 3, Allison was given the heroic ending of a hunter and a final moment to reconnect with her one true love, Scott McCall. While this was sad, Reed spoke to the showrunners about her departure, giving them enough time to properly write her off the show.

How Teen Wolf Killed off Allison Argent

Season 3 saw Scott and his pack facing off against an ancient Japanese fox spirit known as the Nogitsune, who possessed the body of Scott's best friend, Stiles. In the penultimate episode of Season 3, "Insatiable," during a confrontation with the Nogitsune Stiles, Scott and Allison fight off the Oni warrior spirits that the Nogitsune controlled. Allison fired a silver tipped arrow into an Oni as he ripped into her current werewolf boyfriend, Isaac's, chest. Suddenly, she turns around and runs into the blade of another Oni. It's a devastating and shocking moment that sent ripples throughout the fandom.

Scott ran over and cradled the quickly fading Allison in his arms. With tears in her eyes, she reassured him that she was all right, in the metaphorical sense, because she was dying in the arms of her first love. Even though Scott and Allison were not together anymore in Season 3, it was clear that she loved him more than anyone else, and she breathlessly related "I love you" to Scott multiple times before passing away.

Why Crystal Reed Left Teen Wolf

Although three seasons, which was halfway through Teen Wolf's six season run, is not a terribly long time to be working on the same character, Reed felt she took the character as far as she wanted to go and looked to pursue new projects. Luckily, the showrunners were incredibly supportive of her decision.

"Creatively, there were things I wanted to do differently," The 29-year-old actress said to EW about her departure, "I wanted to explore other avenues of film and TV. I wanted to jump into different characters... So I went to Jeff and talked about it, and he said, 'We’ll write you a great ending.'"

Reed is aware that Teen Wolf was still extremely popular at the time and fans would be devastated over her departure from the character, so she wanted fans to know that this wasn't an easy decision.

"It’s so hard for me to let go of [Allison]," Reed said in that same interview, "and I went into, like, a week of mourning because a part of me left with a part of her. She’ll always be there with me. I’m so proud of her. I don’t think I would have been so upset that she died if she wasn’t so special to me. But she really was. It’s so sad. I don’t know what to say. I definitely feel it too. I feel it."

Reed clearly appreciated the art of the show and deeply felt the bittersweetness of the goodbye to the cast and character she embodied. It's a tough call for any actor to say goodbye to a role they felt emotionally-invested in, but ultimately Reed was at a point in her career that called her down other paths. Post-Teen Wolf, Reed can be seen in the TV shows Swamp Thing and Gotham, and in the horror film Incident in a Ghost Land, but for Teen Wolf fans, she will always be associated with the sting of watching young lovers die in each other's arms.
