His exposed foot is completely black (either from gangrene or the disease he has). Considering her insane way of doing things, she's probably gonna die of thirst or hunger by his bedside as he rots away.
Sir Shorts is fleeing the kingdom because he thinks Commoner's corpse is going to be the epicenter of a deadly outbreak, or at least that's how I interpret page 5. But since this wasn't directly translated from Japanese and basically went through some MTL telephone game through Indonesian first (which I don't speak a word of) my interpretation is probably off, if not outright wrong. No idea why he's saying he'll meet the main pair unless he's also dying soon for some reason. But if he's infected by a deadly disease then why flee?
I'm guessing the hammer at the end is a perspective shift back to her and was probably her coping that Commoner's somehow gonna wake up before she does, and instructs him with the note to use the hammer to wake her up. Would've been more interesting if the illness he caught is some kind of zombifying disease and he actually "wakes up" at the end, but as a zombie. Or he somehow recovers and wakes up to her as a zombie, where the hammer is what he needs to defend himself and end her.
So much for what I thought would be a wild ride. Their little adventure ended up going nowhere, and the ending was... one of the endings of all time. At least she's got shoes now. Right?
Hamita cooks some very strange things, but just because something is unusual or has a bunch of twists in it doesn't really mean it's good. Maybe he wrote himself into a corner and lost interest (yet again), but this time chose to actually end it instead of leaving it unfinished, like that book girls story.
I don't even get why this series shifted genres, it's like he got bored of writing a dark comedy / ran out of slave jokes and then on a whim, decided to turn it more serious with shock value moments because he enjoys writing that more. Then he was just winging it until he decided he didn't want to write it anymore and made this... ending.
Commoner died for living a life of being a good person...
The "boy" is clearly the "princess" and if the country is already at war like that shorts is likely right that the country don't have long...
I wonder how long slave-san will stay besides commoner's corpse after it starts to rot... I mean assuming she didn't die there at the end too.
My memory of this is: the the assassin knew that the cat died not by his hand but by the plague which tipped him that the whole village was infected by the plague including the knight and the slave.
The knight died soon after and the slave knew or wanted to get revenge on the princess but did not have the strength left and knew she was dying.
Instead she brought the plague in the kingdom and went to die in the cabin/house that belonged to her master.
The waking up with a hammer to waker her up was her getting ready to die and accepting sleep was her farewell.
I think the knight defeated because he recognized a plague and decided to leave before it spreads everywhere. However he respected the slave's loyalty to her master.
I just realized the waking up hammer is for the knight, the slave wanted to be woken with his hand. The knigh seems started as a slave, and in the arrogant slaves backstory theres more hammers shown... apparently kinda common to punish slaves with hammers.
It's also plausible the knight is infected and knows it and thats the cause of the insomnia. The place that was killing witches and cats suggests that cats are carriers and the knight figured it out and thats why he killed the cat, but too late not to get infected. Though no spots are visible.
That said, the arrogant slave had spots on her wrist below the rope mark, could be bruising from the rope/fight/carrying/dirt but she could be infected as well rather than be an asymptomatic carrier like others have guessed.
Knight realized dude had the plague and gave up on the fight. Same reason he killed the cat cuz he realized it had touched the infected corpse. He left the kingdom because he knew if the psycho slave was left alone, she would go back and enter the palace. If you bring an infected corpse and drop it in the home of nobles, they're gonna die from contamination of the plague. He knew the kingdom wasn't worth saving since the current ruler sucked, so he said fuck it and let it all play out.
That's what I believe is the correct interpretation. Correct me if I'm wrong.
I'm indonesian, I can translate the "Strange boy" line properly.
In english, I'd imagine it's something like "The kingdom is already in the hands of a strange slave."
