Chaos and Gadget hugging during a full moon. This probably takes place during their belligerent sexual tension phase where Gadget still hasn't admitted to herself that she loves him.

Chaos can sense this, but doesn't mind waiting for the girl he loves to come to her senses. And isn't about to reject her loving embrace either. Plus he'll compliment her on the horn ring saying he hopes she wears it more often.

"I really like that ring on your horn. It looks good on you," Chaos said with a smile.

Gadget bit her lower lip, and looked away from him. "This silly thing? There's no way you mean that."

Taking her beak in his hands, he gently turned her face so he could look in her eyes. Chaos ran a talon over said ring, and guessed it was probably made of steel, through he could be wrong. "I truly think it compliments your looks. And it suits who you are. I hope you wear it more often."
