The Mezzanine

This also perhaps twigs on why the character of Paul Ballard being my least favorite character in the show, despite being supposedly the hero.

Oh hell yes. That's still one of my biggest peeves about Dollhouse; they set up Ballard as a rather scary character exactly because he was so sure he was the good guy... and then, at some point, they just shrugged and decided that that's exactly what he was, end of story.
