It could be the soothing lilt of his voice or the fact that he's actively trying to calm her; maybe it's both. Either way, Natasha can feel herself ease, the pounding of her heart slowing into more acceptable territory, and breathing comes easier. Natasha doesn't realize that she's shaking her head against him until she speaks, her voice already calmer with the sooth that he manages to place over her. "You don't have to do that." Because that's not what she wants; she doesn't want to feel as if they, the people who are trying to love her, need to babysit her as she sleeps.

It takes another lingering moment before she's able to look up at him, eyes still somewhat red from the tears that she still can't remember, but she reaches up to brush his hair from his eyes with a tender touch. Not because she needs to, but because she wants the contact right now and doesn't know how to reach out for it in any other way. "This happens sometimes." She takes a deep, somewhat rattling breath to ease herself more. "It's nothing, it hasn't happened in a while, I don't- I'm not sure why it happened tonight, I'm usually under a lot more stress when I...you know."
