@ r2smuse - okay, THANKY. i'm trying to stick to canon on cullen stuff, but i'm not quite as well versed in all the DA lore as i'd like to be. yet. i mean, i played dao and da2 like 10 times each and voraciously read the codex, but i didn't get the dlcs for origin and i didn't read the novels. i can still be cullenite though, right? 
anyhow, this is why i love this thread. all the details about cullen in one place, shared by people who love the character.
i mean, ya know, poetic licence has its place, but trying to stay canon.
Maybe I'm misunderstanding, but Witch Hunt is canon. The thing is... this exchange was said by a couple of gossips who seemed to have an axe to grind with the Warden, so they're unreliable narrators. Plus, Cullen's stay in Greenfell hasn't been mentioned anywhere else. Given the tight timeline between DA:O and Act I of DA2, it was hard to be certain how it fit. But, I've always felt it was likely this episode did happen, since Witch Hunt was in development at the same time as DA2 and features a number of references to Kirkwall and other DA2 topics.

So, anyway, it's nice to see the devs likely intend it to happen that way, even if they didn't say Greenfell specifically.
As for the other bit, I'm still processing the part of how Cullen dealt with the aftermath of Broken Circle.
tbh I'm probably more frowny about the fact that this section renders a lot of my fics innaccurate, because I went with a whole different approach to the issue and now it's all wrong.
Canon has a way to render all our fics AU some day, alas.
See this part makes sense to me, actually.
Pobrecito.
