Part of avoiding thoughts about something was not encouraging opportunities for that something to makes itself felt.

She had thought she'd already reached her capacity for pain and had no room inside her for more. But she remembered having told Archer once that you could not measure love on a scale of degrees, and now she understood that it was the same with pain. Pain might escalate upwards, and, just when you'd thought you'd reached your limit, begin to spread sideways, and spill out, and touch other people, and mix with their pain. And grow larger, but somehow less oppressive. She had thought herself trapped in a place outside the ordinary feeling lives of other people; she had not noticed how many other people were trapped in that place with her.

Alone in the forest, Katsa sat on a stump and cried. She cried like a person whose heart is broken and wondered how, when two people loved each other, there could be such a broken heart.

Through an arrow loop in the wall she saw a familiar horse and rider tearing across the camp toward the healing rooms. Brigan pulled up at Nash's feet and dropped from the saddle. The two brothers threw their arms around each other and embraced hard.
Shortly thereafter he stepped into the healing rooms and leaned in the doorway, looking across at her quietly. Brocker's son with the gentle gray eyes.
She abandoned all pretense of decorum and ran at him.

Brigan was saying her name, and he was sending her a feeling. It was courage and strength, and something else too, as if he were standing with her, as if he'd taken her within himself, letting her rest her entire body for a moment on his backbone, her mind in his mind, her heart in the fire of his.
The fire of Brigan's heart was astounding. Fire understood, and almost could not believe, that the feeling he was sending her was love.

Great! He has indigestion, so let's torture him with cake.
