I have to admit that Solas grew on me. At least he almost always had something to say when I got back into town. I hate the long stretches of silence (especially after finishing the main plot).
at first I thought he was just another of those elvy elves. You know, tree huggers and know-it-alls. And bald. With a nice accent at least. Dragged him along often because I liked his abilities ..and I had not read the description of re-spec amulets at the time *cough*
Then I finished and was blown away by the end, seeing references everywhere in hindsight. I am not that much into lore so I only skimmed the books i found. But after the end I wanted to know everything.
Well and then I saw the romance scene on youtube and well. I guess he had millenia to perfect his kissing technique, right? Almost everyone probably had that scene to prepare for the addon but I want my own so I am on my third playthrough now. Since Feb 15. I was home with a bad cold for a week so I had some time on my hand 
And now I am a bit smitten and obsessed. Cannot get enough of the theories about what is probably going to happen.
