"You-" Melkor stared at the slender Maia kneeling before him, "you have followed me, even here? They will not take you back in Almaren after this, you know, perhaps not even now." he warned.

Mairon bowed his head lower, though he cast his bright, burning gaze upwards. "I do not care," he said, and moved almost hesitantly closer, fingers brushing Melkor's thigh and sliding up towards his waist, "I could not remain without you, please, allow me to come with you, to serve you - to love you."

Perhaps a little free with the prompt as Mairon did canonically go dark as well, but this scene spoke to me.
