Nathan's mind reaches somewhere that Thranduil's can't. He remembers the feeling of someone reaching into his head and changing the world around him, remembers what it cost to fight his way free, remembers people using it against him--and here, he knows someone used Linderman against him, though he can't place who it was.

He knows how angry he'd be if people went in and gently prised away the important memories. The faces of his children, perhaps; how furious it would make him. How he'd look at everyone around him with suspicion. He'd been there; he knew that feeling.

"You treated him none too gently. I need the truth. What you did to him, what made you think he was the one responsible. I can help you, but you need to be honest with me."
