Dom hadn't even thought about getting in contact with Lily if she were being honest with herself, but maybe it was something to consider? But what would she say to her? How could she even start, Lily had married a Death Eater, she'd killed people - Dom didn't know what she could even say to her. "What do you say to her?" She asked Rose, because it was obvious her cousin had something to say, and hadn't had a problem writing to Lily already.
"Do you think they'd let her have a book?" Dom had never thought about the sort of things they allowed for people in Lily's position, because she never thought anyone she knew would be in that position. Leave it to her cousin to prove her wrong.
