If the prince cast a curse on Llewyn after seeing him getting too chummy with Esteban (not for spy purpose), i can understand. I would be disappointed too and try to control the situation if one of my most trusted subordinate getting too friendly with my enemies. Who knew when would that subordinate stab you in the back. He's crown prince, the next king in line, he needs to take precautions
