He knew that Han wouldn't believe him. The other man hadn't been here long enough to know what this place was capable of, how weird things could be. He supposed he could show Han himself. The holos that existed in this place seemed to cover the major events of their lives within the Rebellion. He wasn't sure he wanted to do that to Han. It was better to let him believe that Luke had hit his head or something, better to let him spend some time in this place and see how strange things could be on his own before dropping any of that onto him.
There was, however, something he'd learned that he wanted to get out of the way. Han deserved to know the truth about Luke and his family. The smuggler had saved him from freezing to death on Hoth, he had come back for the Rebellion and saved Luke during his run on the Death Star. If anyone deserved to know who they were constantly pulling out of danger it was Han.
Unfortunately, his plan to deflect went a little well. He couldn't help but chuckle as Han sputtered. The familiarity of it was comforting in a way he'd missed. He just hadn't realized how much until right now. "Who else would risk their lives like that for me?" Certainly none of his pilot friends. They all got along and he knew they'd have his back during a fight but it wasn't the same.
