A somewhat empty episode in my opinion. I'm getting worried this series doesn't really have the kind of drive that would distinguish it from the myriad bulk shows out there. It even knows where it wants to go but somehow we still get episodes like this that are only filled with nonsensical dialogue that we have already heard many times over - and nothing else, more or less. I wouldn't mind if these jokes were running on the side of actual story development but they can't really support an episode of their own.

Trying to get something out of this ep, it seems to me like Ferris might have got corrupted by Ryner. Corrupted in the sense she has forgotten her fear of her brother. Lucile would have killed them both if they hadn't embarked on their journey after Sion instructed them to do so and would be happy to slay anybody threatening Sion. Yet now they are back without any real reason and were joyously talking about killing the king. Though Lucile's absence in this episode could easily be explained by foreseeing how meeting Ryner could recharge Sion's depleted batteries.
