Tara always misbehaved. As a slave sworn and committed to completely obedience she wasn't exactly accomplished. If I asked her to take three steps forward, she would take four and smile at me mischievously. It would have enraged me if I didn't enjoy punishing her so much.
This time, she's not going to get rewarded once I strap her into the stockade. This time, her punishment will be one that she's never asked for, and won't see coming. This time, I'm going to get the dog to help me out so I can watch every expression play across her shocked face as Rex nails her.
