Allison was an accomplished archer and gymnast.
Allison died in Scott's arms after trying to save Lydia from the Nogitsune.
When the pack signs their names on a shelf in the school library, Scott signs her initials along with everyone else as a tribute to her. (Creatures of the Night)
She also appears in flashbacks during the season such as Lies of Omission, A Credible Threat and more prominently in Apotheosis where Sebastien Valet sees her through Scott's memories and mistakes her to be his sister, Marie.
The name Argent is an evolved version of the Latin term argentum which means “silver”. Argent also means silver in French.
Within Teen Wolf, the legend that "silver kills werewolves" refers to the family called "Silver" not the metal.
The Argent Necklace is a silver pendant which is an old family heirloom of theirs. It once belonged to Kate Argent then she gave it to Allison Argent as a gift, telling her to look it up if she wants to learn more about her family.
It has the Argent family crest on it, a snarling wolf and arrows.
Adrian Harris saw Kate wearing it the night they met in a bar, it's the only thing he remembers about her.
