[Fic] "The Guardian in Spite of Herself" chapter 14 -- Naruto

"The Guardian in Spite of Herself" is the sequel to "The Way of the Apartment Manager," which can be found in final form on ff.net, or in beta draft with comments on my journal. It also has fanart.

Here is chapter 14, in which, to the author's consternation, Suisen attempts to perform fanservice, Sasuke decides to act his age, the Amane family will not stop arguing, and Naga fails epically at normal interaction with civilians. (4,600 words)

( The Guardian in Spite of Herself, chapter 14 )

The fourth scene worries me for several reasons. First, I think Naga may come off as cruel instead of just out of her element and lacking a gut-level understanding of the assumptions a civilian woman living alone will make about an intruder in her space. Second, I am trying to show some of how the ninja system plays out among civilians who don't live in a hidden village -- citizens of Konoha, I think, would react differently to a ninja suddenly appearing in their homes, though there would still be an undercurrent of fear. Third, I am basing the shopkeeper's reaction somewhat on my own reaction to surprising a burglar in my apartment this past summer, so I don't think I have any real perspective on how the scene plays out.

Basically, if you have any editing advice, I would be even more grateful than usual.

wherein Liz asks for help with British insults

Question for people who know British slang:

What is a good 1940s equivalent of calling somebody a wanker and/or an arse? I have been told that both those insults are too modern, but I can't think of any alternatives.

watervole suggested 'bounder,' but also said that might be a bit early (though it does have something of the sound of C. S. Lewis, I suppose).

'Bastard' is a bit too strong, 'git' isn't strong enough, and basically I am stumped.

Help, please?

[Context: In 1948, Edmund Pevensie is writing an informal letter to his sister Susan, in which he briefly talks about the man she was... whatever the 1940s equivalent of 'out on a date with' the previous week.]
