Rose didn't attack anyone unless someone lashed out first...or you happened to be her type of vampire, red eyes, sick pale skin, and an unyielding blood lust. She was suspicious of everyone of course and always leery, even in a somewhat peaceful town like Madison Valley. Things could change on a whim here and you had to be prepared for everything...even if it didn't involve fighting. She did sense there was something about the girl that was off. She sensed there might be some anger, maybe fear, but Rose was good at reading people, but wasn't one for prying. She didn't like people prying into her life so why would she do it to someone else...unless it was someone's life on the line or her own.
Rose did see the girl shift her arm as subtly as she possibly could and the bag she was carrying slipped slightly. Rose's stance shifted subtly in response. Apparently the girl thought her a possible threat. Well, Rose was a Dhampir and could very well be a threat and it would take a lot more than just a hit by a bag to take down a half vampire, especially a trained Guardian. Rose smirked at the question though. It was a good question though strange to hear given the random occupants of this town. "Well, probably not here actually. This place is...peaceful. Mostly. I mean aside from crazy weather," she replied simply. "Back home, it'd be needed. Strigoi. Being a Guardian, you had to always be armed to protect your Moroi."
