It depends on where the Sven - Faye relationship is going.
An actual relationship - Probably Marten. She strung him along for a long time, only to turn him down, and now she's hooked up with a guy "she barely knows"? Ouch.
Friend with benefits - Your guess is as good as mine. Could be either of them.
One-night stand - Dora. She'll fly off the handle, assuming Sven used his trademark smarm to get into Faye's pants. It can only go downhill from there.
This is all complicated by the fact that Faye isn't fully agreed in her own mind about what she thinks of Sven.
She claims to barely know him, yet she has acted as his confidante and mentor in his quest to better himself.
She says that she doesn't even like him very much, yet she is often accepting of, or even seeking out, his company.
Methinks the lady doth protest too much.
Whether there is to be any deepening in what is already by any definition a very friendly acquaintanceship will depend on several factors:
1) How uncomfortable Faye feels around Dora and Marten after her confessions. (It was her unwillingness to intrude on them that led to most instances of her intruding on Sven instead.)
2) How dedicated Sven is to reforming his horndog ways. If Faye catches Sven in further philandery, then further intimacy--physical or emotional--may well be out of the question.
3) How interested Sven is in Faye in the first place. We have seen hints that he might have been taken by her as early as
#519, despite the fact that she is neither lithe nor blonde.
4) How masochistic they both are. Seriously, we're talking two basket cases here. They only seem normal and sane because we got Hanners throwing the curve off.
