I was just about to post this. As far as Richard Simmons' fighting, I don't think anyone would be suprised to read that he chooses to slap. My guess is that he couldn't get close enough to bite or scratch.
It's the pro-cons of having a short season. The pros are that they can build the storyline arcs to be as intense as possible, with very little filler. The con is that the season FLIES by. I'd KILL for more new The Shields.
