"Is that not an important thing to do?" Xavier asks it earnestly. A normal DoLL, he knows, would be able to understand and reassure, but he is... well, the way he is. "You are able to do something that many cannot, after all."

He's categorised the scenery by now, and as such, Xavier's focus shifts to Sam. Each expression seems... small, fleeting, but it's noticeable even to him. "Someone takes care of her while you are out working, then?"

The wonder is there - if he can't find Pieces, the likelihood of Sam's daughter being nearby is... low, isn't it? Unless Sam was here before, but that doesn't fit the logical narrative either. He can't understand the logic behind fear, but he does have enough in his database (and his own confused experiences, he'll realise one day) to register that Sam must be worried.
