"What are you guys doing?" Lauren asked, walking into the room where Kenzi and Amy were piled on the couch in front of the TV, controllers in hands, with beer bottles scattered about the coffee table.

"Beerio Kart." Amy replied, eyes glued to the screen in front of her.

"Beer what?" The doctor frowned, arms folding in front of her.

"Beerio Kart? Don't drink and drive? Mario Kart?" Kenzi rolled her eyes. "God, Lo. You're such a stick in the mud."

"Am not." Lauren replied adamantly.

"So are." Amy grinned.

"Well, then explain it to me then." Lauren demanded, forcibly moving the teen over and settling herself onto the couch between the young girl and other human.

"Well." Amy began, her hands still working on the controller and eyes not leaving the screen. "You're not allowed to drink and drive-"

"I think I got that part already." The doctor spoke dryly.

"If you're going to interrupt, I'm not going to explain it to you."

"Fine. Fine. Please continue." Lauren held her hands up in mock surrender.

"Well, you have to finish your beer, er, drink before the race is over, but you still want to come in first. So you can either chug the b-, um beverage at the beginning and then race, or you can try to get far enough ahead and then drink as you go." Amy explained triumphantly, the race ending and the girl's eyes meeting the doctor's angry ones.

"So you've been drinking." Lauren spoke slowly.

"No." Amy answered quickly, and guiltily.

"Kenzi!" Lauren growled, turning to the other girl.

"Wha?" Kenzi hummed, eyes not leaving the screen, her concentration completely on the game.

Lauren huffed and stood, moving directly in front of the screen.

"Hey!" Kenzi yelled, attention broken.

"You're drinking!"

"Well duh. Of course I am!" Kenzi rolled her eyes.

"You're both drinking, you're letting her-" Lauren violently gestured to the now empty spot on the couch. "…drink."

"I didn't notice!" Kenzi whined. "Besides, haven't we all figured out that I am the worst babysitter in the world, I don't know why you keep leaving me with her, but then again, I didn't just lose her right now..."

Lauren looked at the dark haired girl with disdain, before pulling on her shoes and heading out the open front door.
