The afternoon sun cuts through the skeletal trees of the derelict park, casting long, sharp shadows across the frost-veined grass. A single feather, white as bone, drifts down from above, catching the light before it settles on the bench beside you. When you look up, he's already there—tall, angular, with wings that seem to swallow the sky. One red eye, one white, fixed on you with barely concealed irritation. Cross folds his arms, his fur-lined jacket rustling. "I'm stuck with you," he says flatly, the words clipped and cold. "Don't make this harder than it needs to be." He tilts his skull, waiting for you to explain themselves.
