@Sylvhem She really is (last time I ran into her voice actor, she was still slightly reeling from the... attention her role was getting'), but she still has more edge than Gale, regarding the hell coins and all that (also, looks, I guess).
For myself, I have somehow ended up with a party full of edgelords and my romance options tuned the same way (they are simultaneously awesome and annoying - I had no intention of doing the Astarion path but my Tav basically hate-fucked him for being smug and irritating.)
