After Lancet admitted and said the truth, Artemis took his time thinking of whether to act out or stay calm. He chose the later but still he was pissed off at Lancet for going against his decisions especially when it comes to the woman he loved. He could have forgiven him if he did anything, literally anything but when it comes to Aurora, Artemis played no games. He knew many people would be against his decision to marry the love of his life, nothing was new, but still he wanted his friends to respect Aurora. It was enough for other people to be against his decision but it hurt him when it came from his closest allies.
Hence he sighed, looked at Lancet and said, "Now go and apologize to Lady Kholin and make sure she shows up at the ball later." Then Lancet nodded.
"I apologise,Your Grace. For what I did."
"That doesn't matter anymore Lancet, go correct your mistakes and make sure you invite her like a lady. It's an order!"
