A/N: Hello again! Today's drabble is based on a prompt I fell in love with. It's set in the classic anime timeline during the Dream arc, though I admit ahead of time that Mamo is a bit OOC. This piece is rated G.

"You were staring at that new waitress again! Do you think she's prettier than I am or something?"

Chibiusa hung back a bit as they left Crown Cafe, watching Mamoru and Usagi with careful eyes. In her time period, her parents never argued this way. It was almost fascinating to watch the younger versions of them play out the same relationship dramas that she saw other couples go through on a daily basis. Of course, it was also a little sad too.

She eyed Mamoru carefully, the way he walked behind Usagi with his hands in his pockets and his face raised to the sky, eyes closed as if begging for extra patience. Chibiusa believed that he needed a lot of patience to deal with Usagi. Even knowing that she and Mamoru were destined to marry and someday rule the Earth together, she still suffered bouts of childlike jealousy that embarrassed everyone around her. Chibiusa couldn't really understand how they would eventually have the relationship that she had known all her life: that perfect blend of adoration, affection and mutual respect that made them great rulers as well as the most admired couple in Crystal Tokyo.

"Why do you always think I'm secretly cheating on you?" Mamoru finally asked, after they were quite a distance away from the cafe.

Usagi stopped in her tracks and wrapped her arms around her stomach, her shoulders slumping as she curled in on herself. It was something she only did if she was really hurt, like she was instinctively trying to protect herself from pain. For once Chibiusa didn't have the desire to mock Usagi for her clearly insane jealousy. She could see the uncertainty in the older girl's eyes, and she hung back to see what Mamoru would do. He always knew how to fix these kinds of things.

"Is it wrong that I want you to see only me, Mamo?" Usagi asked, her voice small and quiet, so unlike her normal self.

"Ah…" A gasp of surprise issued from Mamoru's lips. "Usako…"

"Why don't I ever catch you staring at me that way? You make it so easy to believe you want someone else!" Usagi cried, her hands balling into fists as she held them against her chest.

Chibiusa's mouth fell open in surprise. Usagi sometimes got jealous, but this seemed different somehow. She seemed to genuinely believe that Mamoru could want someone other than her. Even though Chibiusa teased her about it sometimes, about how Mamo could do better, she didn't really believe it. If they weren't together… where did that leave her? She wouldn't exist.

She was about to step in and beg them to make up when Mamoru did something entirely unexpected. He stepped forward and scooped Usagi up in his arms, casually tossing her over his shoulder.

"Mamo! What are you doing?" Usagi cried in surprise.

"I'm taking you back to my place where I can show you in private what I think of your ridiculous claim that I could ever want anyone else," he said simply, and began whistling as he carried her across the street.

Chibiusa stared after them in wide mouth astonishment as they left her behind. She probably could have followed them, but what would be the point? She had a feeling that this was one of those "grown up moments" that her parents often indulged in back in her time. She didn't really understand, but when Usagi's giggles reached her ears, she figured she didn't have to. As long as it worked for them.

She shrugged and turned back in the direction of the Tsukino house. Maybe she could ask Pegasus what he thought of the situation.
