Derek had known she stole the mask from him back when he was Shadow but he had said nothing about it, instead he let her take it and enjoy it because he had returned it to him before he had got up. Derek kissed her on the lips as he said "Oh I know, and I trust you more then anything to keep me on the right path". He kissed her again before he yawned and said "I think its time to head to bed now, got a busy day tomorrow after all. Want to share a bed with me? You don't have to do anything, I just want to feel you close to me"
