Even a fragile flower can be poisonous. Rosie's character is what we would call a white lotus bitch that's rotten to the roots. She may not be the sharpest tool but she has the blackest heart. She knows how to use her charms and status to make other people as her tools for dirty deeds while keeping her own image innocent and clean. If I were to make a simple comparison, Rosie is a noble-blood version of Rashta from Remarried Empress.
I don't think Rosie's that bad. Well, she sure as hell is annoying but compared to Bridget she is not a villain, but a barking puppy. As of now she did nothing but be petty because someone else stole her spotlight, in this timeline at least.
You could argue that she only killed her sister in the 1st timeline bc she was obsessed with Mikhail's love and even more sensitive/paranoid bc she was pregnant (not to mention that she was spoiled rotten with attention her entire life).
Not saying she is a good guy here, but I think she gets a bit too much credit when she's on the more harmless (albeit saltier) side.
I'm wondering when fl will realize that Rosie's not the sharpest tool in the shed.
