I just want to highlight who “him” is.
Dar’Khan per his description:
Though Lor’themar was found of Dar’Khan, something about him rubbed Sylvanas the wrong way. She did not like how he looked at her, eyes glowing, perfect features in shadow beneath the sweeping brim of his hat. It was one thing to be found attractive; it was another to be regarded as a meal to be devoured.
As Arthas gloats about how beautiful she is in undeath and how he’s purposefully given her body to Dar’Khan to mind…
