Rose was sorry to know that in order to find temporary peace, he needed to reduce himself in that way. Sooner or later she would talk to him, but not too fast. Let him drink if it comforted him, if alcohol could help him accept that Scorpius and the Wand had to be traded for his life. Rose needed all the help she could get because she still didn't know what to say to him and didn't believe she would ever be able to change his mind. It was absurd to think that Draco could abandon his plans just to please her or even someone like Calypso.
