 Tell me about Sebastian. How would you describe him? Sweet, stubborn. He loves to help. He loves running. Parents who know the disposition of a deceased child are more likely to accidentally default to past tense when referring to them. When they're both discussing his likes and dislikes, they're comfortable. All the facial expressions, the gestures, the movements match the syntax and the timing. They speak about all the things in present tense with genuine joy. And parents who are involved with the disappearance, even if they can look back fondly on a child's behaviors, are still having to manage perceptions and maintain deception, which keeps them from being this fluid and unconstrained in their descriptions. So this fear of being discovered mutes and muffles, these expressions that you're seeing right here in this video that look very genuine to me.
