@watercolorskyy You read the Final Note? Aw, I'm surprised you didn't participate in the poll, or leave a comment on my question at the end regarding what you'd like to read from me in the future. (And I'm shocked you had nothing to say about my shameful confession of never having seen a single episode of Peaky Blinders! Are you sure you read the Final Note?)
Regarding your question: as with everything I write, it's up to reader interpretation. The one thing I will never do as an author is spoon-feed people answers; it stifles their imagination. Personally, I think Charlie would be very sad, but he'd understand and just hope to see Rose again someday. ;)
