(Spoilers for 4.11 "A Promise to the Dead")
A few things are unsettling about Kate Argent this season—her were-jaguar abilities, the Berserkers she controls, whatever she did to Derek—but the scariest thing she has done so far is turn Scott into a Berserker.
The scary part isn't that Kate turns Scott into a monster. We could say that Scott was physically a monster already, even if he chose not to hurt people with his werewolf abilities. The scary part is that Kate turns Scott into the polar opposite of what he wants to be. She shatters the heroic part of him, everything he has worked for and fought for, and she is calm about it, calculating. That gave me chills.
Worse, earlier in this episode, one of Satomi's werewolves talks to Liam about how amazing Scott is for earning the power to be a True Alpha, for his leadership, for the way he protects his friends. So just in case anyone in the audience hasn't been paying attention, we have these reminders of everything good in Scott McCall. Over four seasons of the show, we have seen Scott:
- Choose to use his power for good, over and over, even when others try to force him into violent situations.
- Lead others into action and give them hope, even when the odds are against them
- Give everyone a choice in getting involved with the supernatural world, and not judge them for choosing safety
Kate inverts all of that.
She forces Scott to become a Berserker and she controls what the Berserkers do. It seems like she will force him to fight his friends in the finale, so she takes away his power to decide what he does with his power and his desire to protect his friends.
The scariest thing is that Kate is able to unmake Scott the Alpha, turn him against his friends, and use him however she wants.
