That’s what I was thinking too...she’s already confirmed the Duke doesn’t care if she fires people because she’s already fired two other maids so I don’t know why she held off when she knew pretty much immediately that maid was the main issue #-.-) plot convenience I guess ╮( ̄▽ ̄)╭
Why didn't she fire the maid earlier and waited until she caused this much trouble .She already knew about the maid's previous wrongdoings anyway.
