He had been ordered by Rhysand not to intervene, but his hackles were rising. He held back a growl in his throat, his eyes shooting daggers at the red haired male dancing with you- his mate.
His eyes fixated on the other male's hands on your body, holding you, making you smile, pressing against you. Cassian clenched his jaw in anger. He could barely hold back, he needed to intervene. You were his, not Eris'. Definitely not Eris'. What Eris had done to Mor still plagued Cassian, still infuriated him. Eris was a monster and a Coward. Seeing Eris touching you, dancing with you before the entire court of nightmares, seeing him make you smile disgusted Cassian.
He couldn't hold back anymore. He storms across the ball room once your dance with Eris ends and pulls you into his own arms, eager to make you forget your dance with Eris with a dance of his own. Eris merely grins at Cassian mockingly.
