Guilt trap.

Arwen was confused. She married a man thrice her father's age? When did that happen? Her brows furrowed deeply as she stared at her mother, trying to understand what she even meant by that. 

But Catrin only smirked in arrogance. Seeing Arwen flustered and confused, she finally thought he had gained the upper hand over her daughter. Scoffing, she said, "Arwen, did you really think you could hide him and your shameful deed forever? Did you think I wouldn't find out" 

Arwen crossed her hand, her expression calm but watchful. She decided to let her mother continue, curious to see how far this fabricated tale would go. 

"Just when I thought you could embarrass us anymore, you proved me wrong," Catrin continued, her voice dripping with disdain. "Not just you rebelled and married a stranger, you married a damn old man. Do you know how appalling is that? It's shameful. How can you not think before acting on such a stupid idea?"
