Crowning Moment of Heartwarming: X-23 defying her off-book orders from Rice to kill Martin Sutter and his family, when she chooses to spare Sutter's ( actually Rice's) son. After all the effort the Facility went through to break her, that one moment proves her humanity hasn't been completely destroyed.
- The implications are especially poignant when Sarah discusses this in her letter. This event, more than any other, is what triggered Sarah's final Heel-Face Turn, and led to her decision to rescue X.
Sarah: But then you showed me hope. Not when you saved Megan, but when you saved Henry. You showed me that we can chose to be something other than what we are forced to be that we can be something better than we believe we are. And, in that moment, you saved my life, all that matter to me now is that I save yours.
- X-23's training sessions with her sensei. Rather than being the stereotypical Drill Sergeant Nasty Old Master putting her through Training from Hell, the old man shows X almost grandfatherly affection and she responds in kind. He's even openly defiant when Rice tries to warn him against treating her like a person. Unfortunately, this last part probably plays a key role in Rice's decision to test the Trigger Scent on him...
