"I--I didn't expect anything! That's kind of the whole point with skeletons! They not supposed to do anything!" With the undead threat apparently neutralized--for now--Rita's quickly funneling her terror into anger instead (although, okay, fear might still be lurking underneath). Pal acting so calmly just makes her more irritated over the whole situation.
