Re: Iron Man 3 Discussion/Photos/ETC.
I very much doubt fans would call Favs arrogant for developing Happy's character arc with Pepper, especially if they are familiar with that relationship from the comics. In the "Iron Man 2" novelization this is touched on and is part of Happy's character arc as he admits to himself in an internal monologue that he's in love with Pepper. I believe that he questions if he should tell Tony or not and decides not to do so. This happens IIRC about mid way through the novel.
