This is the best Cole I've seen so far. Great job. And yes, they say he is, right next to Solas in the Table pic. I wonder how they'll translate his character to the game. Super curious, since he was so interesting in the novel.
True, usually when they say something like that, it means that the character was first encountered in that game or book. Well, then based on that, the only option is that he is indeed Cole. Because all the other unknown characters don't ring any bells for me.
