Rosa had waited so long to hear more about Violet. She wasn't able to get much information other than she's okay and safe and in her room. She wasn't accepting visitors besides Ash by the time Rosa got there. Rosa was just over the moon Violet was home, safe and sound.
However, she was haunted by the memories of the attack. The smell out burnt corpses, and blood was so thick and overwhelming it was practically palpable. The twisted faces and bodies of wolves infected with wolfsbane. Chewed up arms of vampires, gashes in their bodies and necks. Clear evidence they were bitten by wolves.
