Do you picture them in NY more or the Pitts? - NY. I'm with loud99 - they've outgrown the Pitts.
Do the lesbians, Gus, and JR stay in Canada? - I'm partial to fics that have Gus come and live with B/J later as a teenager.
Do they keep Britin? - No Does Brian keep Babylon? - Maybe Rings? - No Raw fucking? - Maybe. I'm not particular tho it makes for hot pr0ny fic.
How successful does Justin become and how does he do it? - I have the same confidence in Justin that Brian has. Yes he makes it big but i think he would be more versatile - a little bit of graphics and a lot of painting. And Rage of course.
What about the rest of the gang? Does Drew come back to Emmett? - I'd like that.
What about Blake and Ted? - i like the Ted-Brian dynamic but Blake doesn't do anything for me.
And what about Michael and Ben? What are they up to? - i honestly don't care one way or another. I do still enjoy some Mikey-hate fics but i accept that it's not canon after S4-S5.
