Sally's apology to John really struck me as a raw, meaningful parent-to-child apology. She didn't dumb anything down, she didn't lie to soften anything, she claimed all of her actions... he was so young, and Sally reacted to his age not by talking down to him, but by finding a way to describe the whole truth so he could understand
Most importantly I think is how she kept saying that John is a good person. Like...she thought she was about to die. And she didn't spend that time asking John for forgiveness or to remember her in a good light. She dedicated her words to making John feel loved. She spent that precious time giving him something to make sense of it all, to heal somewhere down the line even when she's not there
