Cora shouldn't have to figure it out on her own, but that's how she's used to doing it. She's probably the Hale where losing the pack hit her a lot harder. She was so young when it happened that all of the things that her alpha should have taught her (her mother should have taught her) were learned on the fly out in the real world. She learned to control her wolf because the hunters couldn't see. She learned to control her emotions because emotions were a vulnerability that people aren't allowed to see. She knows she's a predator, she's been one her whole life.

She doesn't want to be a killer.

She knows the world she lives in, and she knows someday she may have to be, but she managed to survive six years on her own without changing the color of her eyes. She even managed to survive what the alpha pack did to her without hurting anyone (anyone but Derek, anyway) thanks to the Beacon Hills pack. She knows that if her control is really, permanently gone she can't do this on her own. But that part of her that was on her own for so long still doesn't know who to trust.

"Are you sure we can't control it?" She presses the heels of her hands to her eyes, brushing away whatever may have been threatening to escape as she takes a breath and pulls herself together. "No anchors or anything to stop the shift?"
