It was things that Alan knew and things that Alan hadn't known and things that Alan had formed half ideas about based on moments seen and heard. He could see though that as she told it, it was all a confession, an act of cleansing, and he wouldn't dare take that away from her, even if some parts of the story were horrible to hear.
As she spoke, as she tore her own words free, Alan did the only thing that he could: he held Telos safe and secure in his arms so that Melpomene could be free to cry and rock and suffer her tale.
When she looked up at him, tale done, Alan was frowning at her as he tried to decide what it was he should say. Should he say 'it's okay'? Okay wasn't really Alan's to give, and he thought it would be flippant coming from him. It clearly wasn't okay, not any of it. He couldn't forgive her for the things she wanted to be forgiven for, and he couldn't apologise from those that had hurt her.
"You have been walking such a long and dark path to come to my door," Alan told her, sympathy in his tone. "There has been so much betrayal on that road, and it's no wonder that you're scared and exhausted."
