Time to add something new to the mix - obviously Trespasser makes me think about Solas, his relation to the overarching story, effect on Lavellan... but I also keep thinking how Trespasser revelations affect other companions.
Especially Cassandra.
I don't think her story in DA is over yet (as in: she's never mentioned again or relegated to a footnote/short cameo), considering that we see her at the very end, actively involved in stopping Solas. And I can't help but to wonder how all this new information about the world must have impacted her.
I have to admit, after I took her as my tank on the journey through eluvians I was prepared to hear more of her dismissive remarks about elvhen religion, the like of which we heard at ToM - yet I've heard none (the only one I've heard that was rather dismissive of elves relying so much on magic was from Vivienne).
Oh sure, we find out rather quickly that Fen'Harel fought against gods he claimed are FALSE, but he is also responsible for creation of the Veil, which shatters many claims and doctrines spread by the Chantry. Still, she was surprisingly reserved about that, supportive of Inquisitor she likes and none of her epilogue cards suggest that she's going through some sort of crisis (though I don't know what happens to her if she's not a Divine, but on a disapproval path with Inquisitor).
Does that means she actually matured further - that she's found comfort more in faith in the world and restoration what's good and helping people, while accepting that stuff about the world and Maker may not be what she believed it was?
I kinda hope that that's it. I think her own faith in the world will be important, aside from faith and hope Inquisitor may have.
....Though I have to admit, in my Lavellan playthrough I just can't not imagine her secretly rooting for Solas and Lavellan to end up being together.
Oh, do I mean secretly? I mean - completely and openly encouraging Lavellan to save Solas.

Lavellan (after she explains what transpired behind closed eluvian): "....So you see Cassandra. I... I'm sorry. Aside from Solas being who he is, this new information about the Veil and stuff... it must be hard for you as well to make sense of it all."
Cassandra (ignores the last sentence as she bites a wet handkerchief): "This... this is... SO ROMANTIC"
Lavellan: "
What?"
Cassandra: "Inquisitor! You have to save Solas!"
Lavellan: "I uh... I thought you'd be angry about... uh, betraying our trust and all."
Cassandra (with fire in her eyes): "Such nonsense! Can't you see what's happening, Inquisitor? The love that connects you doesn't happen every day, so don't give up on it yet! I won't! You two are destined to be together! And I shall help you fulfill your destiny! TO WORK THEN!"
(she stuffs confused Lavellan under her arm and goes to plan the mission codenamed "The Romance To End All Romances").
