I love how there are so many different things at play here--Harry's marriage (now dissolved) and parenting James, his past with Severus, his job and the mystery of the Morsmordre, his relationship with Ron and Hermione. It paints a complete picture of Harry's life as he's forced to make this life defining decision. There's an intensity to his and Severus's relationship, a level of trust between them both--because Harry trusts Severus, yes, but I get the strong sense Severus has to trust Harry just as much. Wonderful work.
