Eleven wouldn't want her to be the sacrifice. No version of her father wanted that. But that didn't change the fact that she had to be. What other choice was there without rewriting time completely? The problem were the variables at play. Even if she killed Elizaveta here, the Master and Romana could still have her... She didn't like this. She didn't like the odds. There were too many things that could go wrong. Yet she had to. As she considered those options, Althea started rubbing the blood on her arm more frantically. She couldn't make it add up. She needed her strings. She needed to map it out but River was there and would stop her and she couldn't!
Whimpering slightly, the frantic teen looked up and jolted as she felt the hand on her shoulder, eyes frantically searching River's features. She knew her time stream. Knew that this was her River. Because it wasn't curiosity and confusion and trying to make sense of her that she saw in the older woman's eyes. Just concern and understanding and wanting to help. As such, the waifish Time Lord Matrix nodded weakly and tried to do as River told her, watching as she wiped up the blood on her right arm, though that did nothing for her left arm. Which she had ended up bringing her hand to her neck and started scratching again in agitation.
The last time she'd been this bad had been after Eleven's death because she had lost his time stream completely. But now there were too many time streams always changing and interweaving and she couldn't focus.
"Tornados are tearing off the butterfly wings in anger for its creation. They're screaming and oh god they're so loud!"
Shaking, Althea stumbled forward and pulled away from River before she started frantically working on the strings all over again, writing down different choices quickly and putting them up and altering the time lines before moving to another one.
"no no no. That can't happen. No. Have to find the schedule. Burn it. Keep her from the pier. Unless the water is the answer? Maybe."
And she was talking about the sacrifice without realizing it. Because there was too much and she couldn't filter and she had to get it out.
