As promised, Thrawn retreats into the hallway while Glenn gets changed. He finds himself grateful that Glenn reverted to an age when his alien cells hadn't become unsafe to others. Though, the vaccine should still be inside him, de-aged or otherwise.

He enters his office again once Glenn's dressed, and of course notices him looking at the artifact.

"I would be careful around that. It may contain dark side energy." And because Glenn probably won't know what that is, he explains. "That power I told you about, many believe that there are two sides to it, light and dark. I admit that I do not know much about the Force, but I have met Jedi, who employ the light, and Sith, who employ the dark."

There's no way he's taking Glenn to Darth Vader, and especially not Palpatine.
