And the mouse nibbles at the cheese.

They are so cute together! I hate tragedies. 

Well sneaking the prince in like this is sure to piss the girls off even more.

Leon, kiddo, you really needed to talk to her and explain before something like this happened. You had time. 
Bro, you can't say you like everything about her and not even begin to understand her.

A few good slaps should do for a start.

Iris still doesn't know, does she? It's been so long, I've forgotten.

Still not out of the woods, unfortunately. They're going to have to deal with the humans when they get out.

Reminds me of the hundred man slayer.

Oh you sweet summer child. People can and do perform terrible acts, especially out of hatred and paranoia. Would the whole party getting killed definitely happen? Maybe not, but their lives would likely be ruined. We've only seen the one evil spirit caught and killed so far, and that was by the barbarians. Who knows how severe the humans and other races' reactions might be.
As for sharing information, he doesn't want to reveal that he's an evil spirit too. He thinks it's too big a risk. Could he do more, sure, but he's not that selfless.

Guy claimed to know the labyrinth well, so presumably he played, but the first thing mc saw was someone else get found out to be an evil spirit like himself and immediately murdered. Hard to risk yourself for another after that.  Guy didn't act like a barbarian and when somebody inevitably found him out they would look at those around him with scrutiny. Or maybe just kill the whole party outright to be sure. So giving him charity and advice was the best he was willing to do for the guy.

Harem requires at least one of every race. 

I... uh... I mean, well, yes that... that could work.

Wait a minute, that's not a katana! That's illegal!

She died, I believe. That was last mentioned like 80 chapters ago or something, so I don't recall the specifics. But as far as high society is concerned the Duke is her biological father and her mother a long standing mystery and source of gossip. 

Oh, right, there's also an anime adaptation coming in January. So that'll be interesting to see how far that gets in comparison. 

Didn't he mention bringing holy ammo specifically for situations like this? And then he didn't use it.

Probably thought it was for the food.

Well, the novel exists. There's even an official translation you can buy. Incidentally, we are looks like 57% of the way through the first volume.

Would be a shame if all of the bones in his body got accidentally shattered.
