Spirit Cole still helps people from the Fade (where he says he'll be most needed). He also promises to return if he's needed on the physical side.
I have to say that's seems a little silly though, since he's still and basically always will be needed.
Spot-on again. It's one thing to have choices and actions influence an NPC's decisions over the course of the game -- that does feel more natural than having it all hinge on a singular moment. But Leliana's quest is pretty much a case study in how not to handle such a development. And yes, the way she ignored a direct order and gets away with it is absolutely not okay.
Now I want to be able to judge her. I mean, she committed murder after all. That shouldn't get a free pass just because she's the Spymaster of the Inquisition. Not my Inquisition, anyway.
I think the devs sold Cass' desire for reforms a little short. She just sits in the middle ground between the other two, who are allowed stronger agendas, despite the fact that she repeatedly speaks about the importance of truth and about how the Chantry needs changes because it failed where it was needed the most and by excluding people.
Yeah, it was clear Leliana was the "throw everything in the air and start again" option, Vivienne was the "keep everything exactly as it is" option and Cassandra was supposed to be in the middle. But she doesn't seem "in the middle" enough. At least I didn't think the epilogue matched what she pitched, exactly.
Likewise. It's rare we really get to do that with anyone, but Cole with his unique circumstances could probably do with affirmation more than most, regardless of where he is on his journey. And yes, the assumptions ... I was annoyed that the companions treated keeping the Wardens around as if we were welcoming them as allies who hadn't really done wrong, for example, with no option to explain why we keep them around.
Good example with the Wardens. At least the mage/templar choice has 2 options within those 2 options, but there are still multiple reasons why you could conscript or ally with them.
Thank you. It's always reassuring when someone on the outside of the matter sees and understands it too. I heard about EDI, though I never could get into ME myself, and it sounds like they handled that rather badly too.
You're welcome, I'm glad. It was... I don't know. I don't want to derail the thread, so I'll say it did feel like it was a bit shoehorned because "person = relationship". Luckily they didn't do anything remotely similar with the other AI, Legion. Though now the cynical side of me is thinking: "Female" AI/person = relationship. Anyway, I should move on! 
I wish they had focused more on the existing friendships instead. The companions had lots of unique and sometimes very close bonds with each other that could have been revisited. And I'll always be bitter that staying together as friends is something that rarely seems to cross the writers' minds.
Especially the "staying together" part. Why does everyone who has supposedly grown very close have to scatter to the winds after every game? 
If you look at Sera's little note list by her place in the tavern, she gets excited when Dagna first shows up. And in Trespasser, she's still talking about her in her notes, and it sounds like they do know each other well. (Sera is sketching her.) We never see them together, but it's implied.
Yeah, I read it. But her interest never seemed any more than platonic; she was just relieved there was someone "fun" in the Inquisition. So all of the development came in Trespasser, all in a large dump. I'm not really saying it's a bad pairing, I guess I just want to be shown, not told, as they say.
