I'm now 5 episodes into the 3rd season.
It's fun seeing all those sga/sg-1 actors pop up occasionally: Jessica Steen (the original dr. Weir), Andee Frizzell (several Wraith queens), Ben Cotton (Dr. Kavanagh) and Don S. Davis (General Hammond).
One fun thing I want to tell about Andee; I saw her at the Pegasus 3 convention. She's a fun and lovely lady, and when she was on stage she was telling her stories and answering questions very enthusiastically. At some point someone asked what it had been like playing nurse Glockner in Supernatural, and she got all 'Oh man, Jensen Ackles, I tell ya... Oh! You remember how I couldn't answer that question earlier of what I'd definitely want to do before I die...?! Well...' at which the audience whooped knowingly while she grinned and nodded.
Heheh.
So far I haven't managed to read any Dean/Sam, because I can't wrap my brain around Wincest. They are such brothers! But I've read & enjoyed my first Jensen/Jared *grins*
Everybody who's in the fandom and into this rps pairing has probably already read it, but I'm linking here anyway, because it's deliciously long, and slowly building, and warm, and sweet, and fun:
