Faye and Sven, OMG kissing... Get real, folks!
I like Sven, I really do, but he and Faye are not going to become a couple. Not because of Faye and her issues, but because I think she is the first female friend Sven has ever had. In fact, I get the idea she's becoming the first real friend Sven has ever had, period. So I see Sven himself being an obstacle to this, at least in the near future.
It seems much more likely that Faye will take a chance on Angus, who is, if nothing else, far less threatening. It will last about as long as Steve and Ellen did, but it'll be a start.
However, as far as likelihood goes, I think Faye's more likely to start dating the allosaurus or DeathBot 9000 as she is to date either of these two. And that's a good thing, because Faye does not need to add a complication to her emotional life right now. I think Martin and Dora being a couple are actually good for Faye because they a) have gotten her off her butt and into therapy and b) have changed Martin from a possible complication into a pillar of support, which is what Faye really needs. I think Sven is becoming one of those pillars, too.
As for Faye and Steve, do you people *want* Faye to kill someone? Steve seems a nice guy, but he's almost as shallow as Sven pretends to be. On the other hand, Penelope and Sven are a possibility, if Penelope ever quits CoD or Dora decides Sven has finally grown up. Penny is what Sven really needs and vice versa. He brain will keep him in line, and he will convince her she's attractive physically as well as intellectually.
So Faye will be the Nun of QC, at least until she straightens herself out. I hope so, anyway; to do anything else would be horribly selfish and unfair of her. I think Faye has neither of these qualities in any great abundance, so it may well be strip 10,000 before Faye starts dating. Let's hope Mr. Jacques sticks with us for that long.
