Here is the passage from the original novelization:
"The Eye cocked its head, making an eerie squealing noise. It took a moment for Kylo to realize the creature was laughing at him. “No need for that,” the Eye said. “Do you really think my lord would have left it in the guardianship of one who could be swayed by a trick of the Force?”

No, he supposed not.

“You’ve been seeking it for a while, yes? I must warn you, our fiery planet burns away deception. If you proceed down this path, you will encounter your true self.”’
