Make up a lie to damage her marriage

Your voice drops to a whisper.

"Lady Stark, I have been weighing this information up for a short amount of time, but feel you need to know." Her dismissive look turns to one of mildly hidden curiosity, "I walked in on Lord Stark the other day when Lord Royce was visiting, accidentally stumbling across him in the aviary." You pause, and let the moment linger - you find her curiosity and anxiety delectable.

"I'm sorry, my Lady, but I caught him with Lady Royce. They were... intimate. They didn't see me, but the things he was saying to her. That he wanted to do to her..."

She stumbles against the nearest wall and you move to brace her, placing your arm on her shoulder.

"What did you just say, boy?" her voice is cold, but somewhat faltering.

"I'm sorry, my Lady, but I felt you needed to know."

She recovers enough to move towards the doorway to the bedchamber she shares with your Father, her movements drunken, and walks inside.

"Not here, boy. Inside. Tell me everything".
