"It ain't," he agrees, closing his eyes and frowning.

But, what can they do?

Nothin'.

He hates this helpless feeling, he's felt it much too much and it wears on him more and more each time.

He's not supposed to be helpless, he's supposed to fix things and set them right; to help people and protect them. He hasn't been doing that, hasn't been able to, and now look where they're at.

Now isn't the time to let himself get bogged down in that guilt, though, the grief is hard enough. So he focuses on Kate, her closeness, and comforting her.

Stroking her back, and pressing his cheek against her hair, he stays strong for her.
