Here's the reason why Allison Argent (Crystal Reed) was killed in Teen Wolf's cast, it was technically an ensemble project that introduced a host of other relatable characters including Allison, who became romantically involved with Scott.
One of the show's core characters, Teen Wolf developed Allison and Scott's relationship. Outside their affair, she was also a great asset to the growing McCall pack due to being skilled with a bow and arrow. Complications came in, however, when Allison learned of her heritage. Apparently, she hails from a long line of werewolf hunters, which made her conflicted about her association with Scott. The pair never got back together after that, but she continued to help the pack, especially during the emergence of The Alpha Pack and the Darach. Eventually, she moved on to a new relationship with Isaac Lahey (Daniel Sharman).
Frankly, Teen Wolf could've continued playing out Allison and Scott's relationship amidst their break-up, with the former still having a lot more interesting stories left to tell for her character. That's why fans were shocked when she was written out of the show and killed off in the season 3 finale episode titled "Insatiable." The character went out heroically as she died of a fatal stab wound from an Oni sword. It was a bittersweet farewell to one of the show's coolest characters, but as it turns out, the decision to end Allison's arc in Teen Wolf wasn't anyone else's decision but Reed's.
Crystal Reed Left Teen Wolf For More Dramatic Roles
As the actress herself explained to actors who left Teen Wolf on their own, Reed shared that she wanted to explore more things creatively as she feels the need to do something more age-appropriate considering that Allison is technically 12 years younger than her in real life. The show's creative team was ive of her decision, with showrunner Jeff Davis even promising her a great send-off which he followed through considering how Allison went out. Reed recalled:
“I felt like, creatively, there were things I wanted to do differently, and I wanted to explore other avenues of film and TV. I wanted to jump into different characters. You know, I’m 29. So I think the age difference was something I wanted to change as well because she’s 17. I love the show so much. So I went to [executive producer Jeff Davis] and talked about it, and he said, ‘We’ll write you a great ending',”
The actress' next outing after wrapping up Teen Wolf was in the indie film Too Late (2015), she then followed it up with the horror feature, Ghostland (2018). Still, Reed made her way back to the small screen. After a guest appearance, she booked the role of Sofia Falcone on Fox's prequel DC show, Gotham. She played the character for 14 episodes in season 4. After that, she remained in the comic book TV world nabbing the lead role in DC Universe's Swamp Thing.
How Alison Is Returning for the Teen Wolf Movie
Despite Allison's character biting the dust in season 3, Crystal Reed will be reprising the role in the Teen Wolf revival movie — but how? It's odd that creator Jeff Davis would decide to bring Allison back into The Vampire Diaries franchise have made something of a sport out of character resurrections. There are even rumors circulating that suggest Allison will go back to her werewolf-hunter roots and return as an antagonist. Regardless of how she comes back, audiences will be happy to see Allison Argent return in the Teen Wolf revival movie, even if only in flashback form.
