It seemed only natural to Fenris that he should come to see Hawke. She'd been through a lot, and he'd been remarkably absent for much of it. The killer was caught, dealt with, and her sister seemed on the path to recovery. He had no more reason to hide.
And he had reason to talk. He'd had more dreams, and woken up to a sword leaning against his bed. He'd thought of bringing it along, but had realised that carrying a giant two-handed sword through the city might've attracted a fair bit of negative attention.
"How are you coping, Hawke?" He'd slipped in fairly silently. He was getting proud of his ability to sneak around.
