Yeah, that would probably work better. I mostly didn’t realize how big of a space there is to be filled there. But it’s definitely doable in a seamless way.
A slight reword just came to me that might work even better, particularly in terms of the flow of the conversation:
“I failed the galaxy. My greatest fear.”
This has a more logical progression:
“I was wrong. I failed the galaxy. My greatest fear. What are you afraid of?”
