Introductory Eppescest

[pardalote.livejournal.com]

I have a friend who is tentatively willing to be tempted to the dark side (by which I mean she said "send me a few recs and I might give it a chance. No promises.")

Now, while I'm perfectly willing to go through the arduous chore of re-reading all the excellent Charlie/Don fic that's out there in the name of a good cause, I thought some of you might have some suggestions. So, what Charlie/Don would you recommend to someone who hasn't managed to get past the incest squick and into the angst?

I should note that I have no idea whether S3 has shown here or not, but if it has I don't think she's been watching all that religiously. And she's the kind of girl who's adamantly anti-spoiler, so it'd be best to stick to S1 and S2. (One hurdle at a time, right?)
