Still reeling over teen wolf, but let me try to be coherent about Allison right now.
That was not Allison tonight. She didn’t resemble the Allison we know. That girl shooting arrows mercilessly, ready to kill without question, the girl who has become a soldier for her grandfather, that girl who gave her dad some major attitude while flippantly dismissing him and his code. That’s not Allison, that is Kate.
We’ve seen Allison/Kate parallels before, but I think this is the first time that Allison is actively trying to channel her aunt, to take on her attitude, her mannerisms, her belief system, because she thinks that’s what strength is. She’s becoming Kate, wearing her personality like a suit of armor, because Kate was the first person to tell her that she could be strong, that all she needed was a reason, that she could surprise herself. Allison’s whole arc has been about feeling powerless and wanting to change that. That nightmare vision from Lydia’s party was Allison splitting into two people, the powerful and the powerless, and she doesn’t know how to reconcile those two people. She thinks she has to be merciless in order to be powerful because the strongest examples in her life of powerful women have been her mother and her aunt, and they are both dead, because of the same family, and Allison feels that she needs to remove that family—and the pack, by extension—if she ever wants to feel safe or powerful again. She thinks she has to kill the weaker part of herself—which, to her, is the compassionate part, any quality in her that would stop her from striking down her enemies before they strike her down—in order to let the powerful leader, the one holding the crossbow in her hallucination, take charge and save herself and every one she loves.
On top of that, she has Grandpa Argent encouraging her that this is the right way to be, the same way he probably encouraged Kate, and man, she is feeling such a rush of power and rage right now that nothing can stop her, not even herself.
