It takes literally biting at the inside of her cheek for Kate to stay quiet and patient when Yelena trails off. It's clear that isn't actually the end of her thought, and Kate doesn't want to interrupt or influence whatever clearly heavy thoughts Yelena's having right now or any decision she's making about sharing them.

Likewise, she does her best not to move again until Yelena does, but that's pretty immediate once she indicates she's still okay with being touched. Maybe Kate should still ask, but she can't help it, almost immediately wrapping her arms around Yelena's shoulders in turn and tugging her in tight. Thinking of what to say takes another minute, this is more than a bit more serious then any comfort Kate has practice giving, and her go to was always distraction. "Okay. Okay. I don't really know how to make you feel better about that or less worried immediately, but I won't go anywhere till you want me to, okay. I mean I'll have to go feed and walk Lucky tomorrow, but you can come with me, obviously. And whatever happened before, whatever got ruined? There's no way that was because of you. It wasn't your fault. No way."
