Prompts: 30. "Please don't use my toothbrush again." And 62. "Are those my... aaargh gimme those back"

Having a 14-year-old teenager as a little brother was a mess. You two were always teasing each other and Bruce had to put up with a lot of behavior that wouldn't have been appropriate with him if his parents were still alive. Fortunately Alfred was there to calm you two down if you had a fight - at least he did it better than Bruce would. Dick was a nice guy and you loved him very much, but like most brothers, he loved to mess with his big sister - and you weren't innocent either, you had provoked him with teasing him too.

One day, you noticed your toothbrush had been taken out from your shelf and instead, it laid beside Dick's toothpaste. You quickly pieced the parts together and marched to the training room, where Dick was beating a mannequin with his pole.

"Dick, please don't use my toothbrush again." you groaned but Dick just raised his eyebrows at you before leaning on his pole and smirked.

"Bruce told me to brush my teeth but I couldn't find my own toothbrush. You know how strict Bruce can be."

You scoffed. "Yeah, but that was brand new and now it has junk from between your teeth on it!"

"Y/N, Dick - what are you fighting about again?" Alfred had appeared beside your side and you held your toothbrush in front of Alfred's eyes.

"He used my toothbrush without permission!"

Alfred sighed, taking the toothbrush from you. "We can always buy a new one. Please, master Bruce tries to work upstairs and your continuous little fights disturb him." he paused. "Actually, Y/N, why wouldn't you join me? We could go to a store to buy that toothbrush right now."

"Fine, let's buy a safe too. I apparently need to lock some things there so Dick won't have them."

Alfred chuckled. "That's a good idea. Less fighting at least."

"Dick, who's this?" you grinned at your sleepy brother while holding a folder with multiple pictures of a girl. "She's pretty."

Dick stared at you and the folder in your hands, not immediately registering what were you talking about. He had just woken up and was now having breakfast and looked like he wanted to sleep five more minutes - but then it hit him.

"Are those my... aaargh gimme those back!" he bellowed and lunged at you, but you dodged him with ease, taking out a few polaroid pictures of the girl and Dick together.

"Awww you're so cute! What's her name? Where did you meet her? Does she like you too?" you smiled at Dick who was now growing redder and redder.

"No! She's... she's just my friend!"

"Sure, she's a friend. And you just happen to have a big folder full of pictures of her and you together? Oh, in some pics she kisses you on the cheek... and there are love letters too... an interesting case of a friend!"

"Y/N-!"

"What's happening in here again?" Alfred entered the room and his gaze flickered between you and Dick, who ran out from the room and you hid the folder behind your back, knowing your wordless promise for each other - secrets won't be spilled.

"Nothing is happening. Just our usual teasing." you grinned at Alfred who shook his head, seemingly believing you.

"Master Bruce is having a hard time with you two..."

And as he exited the room, you let a grin to spread on your face once again, as you gave another glance on the folder in your hands.

Your little brother was growing up, and that almost made you feel sad. It meant there wasn't much time to tease him as much anymore.
