Thanks for the warnings. Since just your descriptions -- which I asked for and expected -- are making me shake, I'd better skip the whole episode first time 'round. Shit.
I wouldn't dream of reading or watching any of The Girl with...series.
Oh! Is that the episode with Kiri Te Kawana? The opera singer? I'll have to watch at least that part eventually!
I don't think you have to skip the whole thing. Most of the episode the guy is just acting like a confident douchebag like most guys do when they try to chat up women who are not interested. The way he turns violent is very sudden and jarring at the very end.
