He's prepared for that question, but it doesn't come. He might be curious, one day, to know what his grandfather thinks about him having been named after Obi-Wan Kenobi, with all the innate pressure that entails even if it hadn't been done in the most immediately recognizable form. But it's not something he wants to get into right at this moment.

The insights about his grandmother are far less expected. "No, I didn't know that." Being from Naboo, yes, but not the rest. He knows something of Padmé Amidala, but nothing too specific, similarly to how he knows relatively little about Anakin Skywalker. Any stories from his mother or uncle's lives centered on the people who had adopted them... and considering how they had entirely concealed his relationship to Vader, that calls into question what little he does know. "I was never told much about either of you."
