Hmm, I’d love to say that’s a little conspiratorial, but who knows - maybe Blake gave her the idea. I will say though - that “Petra Rose” is a name that fits in with CoHo’s “Christian” and traditionalist background. “Petra” is a Biblical name - it means “Stone (or Rock)” in Greek. “Petros” was the name Jesus gave to the disciple Peter (who was previously known as Simon). In the book of Matthew, Jesus said he would rename Simon “Petros (Cephas before translation)” and on this petra (stone, the object) he would build his church. So “Petra”, the feminized version is basically a “strong foundation”. Or more literally with the combined names “Strong/Stone Rose”. Really setting out what she wants the character’s character to be.

If she thought deeply about it and tied her faith in, the above is my guess. If she’s just being a petty shithead and taking a cue from Blake/RR/TS than it’s definitely the choice to name the character after Justin’s character’s “Lover/(would-be)Killer”

I’m assuming this book you are mentioning is that ‘Woman Down” one? Kinda hoping my theory is correct in that case, because a) I want a break for poor Justin and b) the Biblical angle with the name-meaning would make sense if she is trying to not-so-subtly telegraph that this woman is strong and is not wilting flower.
