Asterion didn't sweat all that often, especially when it wasn't even that warm out. Seeing his sweet sister again, after so long- Well it turned out it was one of the few things that could bring it out in him. Ariadne had been one of his only comforts in the labyrinth. He starved and raged for years in the dark and Ariadne was the one to minister to him. On very rare occasions she sneaked him food.
And then she betrayed him and brought about his death, sure, but his entire life was torment. Asterion saw it as a mercy. He also knew she might not realise that.
When he caught sight of her, all bright in the sun, his heart skipped a beat. Of people Asterion loved, Ariadne was second only to their mother. And she was here and walking towards him, and he could see her beautiful face, not hidden away by shadows.
He moved closer, though he didn't crowd her. He knew she was probably going to be as afraid of him as everyone was. "Ariadne," he said, his voice soft and filled with something like awe. "Beautiful."
