Aye. This series actually surprised me. I thought it would be but a loli fest, but in fact, while cliched, it's actually very solid. This episode was no different. You knew from the moment Karen dropped the pencil how the rest of the ep was going to turn out, but when things are done well, I'm not really even bothered by such predictability.

I've been also wondering about that Karen-brother situation. It's taken over the top but I think it just tries to underline the fact Karen really does have a psychological problem of not being able to be in the presence of boys. And I reckon she's really sorry she can't meet even her own brother, and tries to fix that. In the mean time, though, she tries to make up for her inability to stand meeting her by the multiple letters. In a sense you could say that if your own sister/brother couldn't stand you company it is kind of insulting. From that source rises the creepiness of how it's depicted. However, I think it's much more believable than all those incestuous relationships around.
