do whatever you want that fits you! i'll roll with it! dorcas is very careful about revealing her allegiances and acts like she isn't too invested outside of being sympathetic. she kind-of gets away with it because of her golden bubble (her family is wealthy), but! her dad is a pretty high profile muggleborn so definitely a target. she'll really look after emily and get her in to all the cool pubs and clubs, etc! so maybe they've really started to bond since she graduated?
