The news that you went running off into the mountains for reasons you can't explain without making him angrier and (from his perspective) endangered his magical assets by picking a fight with a wyvern will put him in a better mood?

And in Sieghard's defense, if he had just stood by and let him have Sanne's tongue cut out, he would've succeeded in at least getting her out of the dungeon. I just didn't expect him to make the jump from "Rorik has silver? I want silver" to "Elsa is somehow behind all of this" and at that point, I only saw three options. Say she was, which would make him mad; Say she wasn't, which he wouldn't believe; Or play dumb and act like Sieghard has no clue what relevance Elsa had to any of what was discussed, which didn't work, but still seemed like the best choice of the three.
