"I can explain."

Your girlfriend has always been overprotective of you. You were somewhat aware of Holly’s well meaning, aggressive negotiation tactics. You learn how overprotective she can be when she accidentally reveals that she can grow into a giantess when she's shaking down someone who's wronged you. Now she has to explain herself to you and reveal how long she's been intimidating people in your life.
