This section of the fight with Corypheus, where he pops off about the vallaslin? As soon as he said "look at you, wearing slave markings on your face with such pride," I was completely furious.
You bet Lavellan's proud of them, you ass! If she wasn't going to be ashamed of them for Solas, she certainly isn't going to be ashamed of them for you!
(Also, that was Solas popping into stealth right there on the stairs. I always give him the Ring of Doubt that you can pick up in the shrine to Sylaise on the Dirth. But it was particularly funny under the circumstance, because I bet he wanted to crawl under a rock about that taunt.)
And then the crack about calling the elves 'a race of sniveling cowards that shrank before Tevinter power'?
Such a bad move on his part. My Lavellan was immediately thinking of Crestwood, and had a lot of pent up aggression about it, and he just made it worse for himself.
Who's a sniveling coward now, buddy?
