The scream is trapped behind his smile. He keeps it locked there when Macha throws herself at him, wrapping her arms around his neck. He bites his lips until they bleed while Hawke and Cullen discuss what will be done with him, but the scream stays where it belongs.
He swallows it, letting it swell his throat until his throat burns with the effort of keeping it in. He feels it settle lower, behind his sternum like something possessing him.
And it is that thought that breaks his smile.
He excuses himself almost at a run, he clatters down the stairs in the Gallows, crashing through doors, going deeper, deeper, until he reaches the entrance to the tunnels that no one is supposed to know about. Where no one is supposed to know the smugglers bring more lyrium for addicted men and women than the Chantry would allow.
Where no one but a few dwarves will hear him when the scream finally erupts from his throat like lava thrown from a volcano, torrents of sound scalding away the fear and anger and pain that he had hidden because he had responsibilities, he had a family, he could – not – break.
The scream burns away some of what he has hidden, but the memories will be with him always. Keran realizes then that it will never end, he will fight the demons of memory for the rest of his life.
