Tearon Bleanix does not respond to, "Who is Princess Lenya Thex?"
He should say: "The Princess Lenya Thex is the daughter of His Royal Majesty, King Tearis Thex of Felwithe. She was on her way to Qeynos when we believe she was kidnapped by Carson McCabe, the governor of this vile city. I await the paladin from Felwithe."

He responds fine to, "All is not bright above the clouds"
For context, I am a halfling druid with kindly faction.
