Does Camille know what happened to Vi's parents?

Upon taunting Vi, Camille says: "Ever wondered how you became an orphan?" While this could mean absolutely nothing and just be taunt, it makes me wonder if maybe Camille killed Vi's parents. Being Camille is older than she looks, its quite possible she's old enough to have been doing her thing when Vi was an infant. Other than that line, there is nothing else that supports this theory, but it was enough to get me thinking.
