The first time Sarah sees Alison in real, life threatening trouble, she nearly breaks.
It was more like she sensed it. She and Alison were nearly miles away, and then something clicked in her head, told her something was wrong, that she should check on Alison and make sure she was okay.
And later on she'd thank the part of her that knew. Because she arrived at Alison's house at the exact moment to save her from the gunfire, to tackle her to the ground while Alison looked up at her like Sarah was some sort of broken guardian angel.
Sarah tore her assailants apart angrily.
"If you ever touch her again, you'll regret it." They walked away. Dyad knew what Sarah Manning was capable of, even if they didn't fear her.
Sarah, of course, meant every word.
