Oh god the backstory on how Nagi's parents met and became lady and butler was great. Those scenes seemed a little random at first, but they ended up connecting most of the plot points that have been present for this season so far. So now Nagi has to get the black camellia from her father and... give it to Ruri? For some reason? I at least expect a better explanation before something like that can happen.
