For a first-timer, Jim is definitely doing a decent enough job. Hunter works on his own canvas, a small smile as he can start to see that Jim is creating a night sky. He can tell when a memory takes him, since Jim just lost focus and started to stare at the canvas.

Then he started to speak softly, only his side of the conversation is heard by Hunter. He has to wonder who Jim is talking to in that memory. It sounds like it might be one from his childhood, so that at least narrows down the options.

It doesn't sound like this is a bad memory, but Hunter is prepared to take action if Jim starts reacting violently.
