You Qian
For someone who is directionally challenged she sure can find her way back to "sister". Is she staff no 3? Or will Lonemoon be replaced cos sister can roast chicken and not just cook pig's swill? I suppose Lonemoon can become the paymaster. Also yi Qing is quite the character. He knows how flawed his master is yets worships her lile crazy. Probably found excuses for everything she does.
