What is it you find improbable about Sven? If it's his job remember that QC hasn't really had a very plausible career for any of the characters since Marten left his office-bitch job. Coffee of Doom is owned by one of the main characters and seems to happily churn out a profit by itself to share amongst the others. Hannelore used to have her counting things job but I assume that's been replaced with her parents supporting her lately. Marten and Tai seem to have things pretty easy at the library. So while Sven's fantasy job may seem improbable it's somehow fitting with the theme of QC.
I probably should have said mildly improbable.
I suspect my difficulty with Sven lies in the fact that he doesn't seem to be written consistently. On the one hand, he's an insensitive twit who's had, so far as we know, absolutely no opportunity to make any sort of character growth. On the other hand, he always seems to make the exact correct move with Faye. I can't make the two jibe. At first, I, too, thought I saw signs of growth, but now he simply seems to be a growth of the wartish variety. He probably is actually helping Faye, simply by being relatively indifferent to her, which I could buy, except he hasn't always been. Again, a bit improbable: do you go from being concerned and friendly with someone who has made you realize women are people to slotting her into your original category of pleasure-source? (Hmm, I may be providing my own answers here. I'll have to think about it)
Looking at this written down, I can see that it does perhaps describe a real, truly inconsistent flesh and blood person. But all of those who've I've known who have resembled Sven have all had a very very raw place in their makeup that anyone who gets too close to them invariably rubs, hence the shell in the first place. I admit we saw a little of it back when Faye rejected Sven, but that may have been simple childish pique at being balked.
All of Jeph's other characters who stick around for more than fifteen strips, yes, even Hannelore, are fairly consistent. Sven doesn't seem to be. In other words, he bothers me.
Anyway, there's my long answer to a comment inspired by reading too much Andrew Greely (specifically,
The Bishop and the L-Train) lately.
So who do you find improbable in QC land?
Edit. Yikes! I meant a long
explanation of a brief comment.
My comment, not SuperSUGA's. I need a proofreader.
