I think Faye's thinking on this matter may not be entirely clear.
I mean she pactically attacked Sven during their first, err, encounter, but she seems to beleive that Sven has an almost magical power to get into ladies' pants.
One might even say she thinks he's some kind of
Svengali.
Put if you look at what actually happened, Faye caught Sven comepletely by surprise. You would think that if he was using some kind of magical seduction ability, he at least would be able to tell when it's about to take effect.
Could it be that Faye's perception of that evening has been altered by her feelings about what where it ultimately led, and may even be in denial about her responsibility for the evenings festivities:
"I didn't get tipsy and horny and decide on a whim that it might be fun to jump the bones of my best friends brother, Sven used his magical lady catchin' power to make me get all higgledy-piggeldy and lose total control over my choices. Repeatedly, over a period of several months. And then he dumped me, the fucking pig"
I think Hannelore and Sven will have a delightful (and completely chaste) time on their "date."
Either that, or Hanner's's's horny juices are about to overcome her crazy juices, and all she needs is a little vino and the right mood lighting to put her over the edge. She may even be unconsiously engineering such a situation. Yes it's completely out of character for the Hannelore we know and love, but do not underestimate the power of horniness combined with alcohol to make people behave in unusual ways. (Anyone ever seen a wet t-shirt contest?)
That doesn't mean the crazy juices won't take over after the horny juices have been, err, drained, as it were.
Something tells me Dr. Corrine is about to make her next boat payment. (Unless she has to spend it all on yarn to update the chart, which has surely become much more complicated!)
