A while ago I posted that the saddest ending for me would be seeing Solas become corrupted in a way that he betrays the very moral principles he professes to uphold. Well, shit. I really think he has gotten into that territory. I suspected he created the veil and that his plan would be something that endangers modern Thedas, but actually seeing that play out is very, very devastating. The way he talks about it, saying, "I am not a monster. If these people are to die, I would at least let them have some comfort first." (Totally not an exact quote.) It makes him sound like he is a monster who is rationalizing his actions.
I can see his point of view. He has lost everything and the pain of that loss is driving him towards a desperate attempt to restore what was. In his pain he does not want to see that the world has changed and that there are new, real people living in it now, and these are living beings that he has to destroy. Still doesn't make it right.
I was thoroughly spoiled and was dreading the scene where he takes Lavellan's hand, but compared to everything else he said in that scene, the hand thing ended up looking like a gesture of kindness, by far the most humane thing he did. And that says a lot.
So, all in all, I feel so, so, so sad for him. But I did like the option where the Inquisition (I totally kept it running) is hunting him to try to save him from himself rather than defeat him.
And last but not least... Oh, boy, TEVINTER! I literally screamed with excitement when she struck her knife on that spot on the map. This complements my particular headcanon so well.
Iron Bull's betrayal... Meh. I really liked his character, but he acted so weird from the start of the DLC that it was just obvious it was coming, and amidst the emotional turmoil of everything else I guess I didn't have any feels left.
I need time and Nutella now.
