She breaks down and tells him everything.

"What do you mean, her younger sister?" Jeff asked.

Elizabeth bit her lip and fiddled with the end of her pony tail. "Uh, like, well..."

"Just spit it out!"

"So Ms Hastings, I mean, Megan works from home a lot. And people come and see her and stuff. So I sorta kinda pretended to be 19 so her work colleagues wouldn't think I was her older sister, cause that would be, like, embarrassing or something." She twirled her hair in her hand, absent mindedly. She'd felt a little spacey all day after talking to her sister. She wrote it off as a consequence of not having any coffee that morning.

"So she told you to act like a loopy 19 year old?"

"Well, like, I think it was sorta my idea?" Elizabeth clarified, though she truly wasn't sure.

Jeff mimed a facepalm, and slowly shook his head. He chuckled, "Well, you're certainly doing a good job of it. As long as you're making money, I guess it's ok. A little weird, but ok."

Elizabeth brightened, "So you're like, ok with me spending the night there some? I mean, like, I'd still be living here mostly, and stuff."

Jeff shrugged, "Yeah, I guess its fine, but I'm not thrilled about it. You're certainly taking this whole pretending thing seriously."

Elizabeth bounced with glee, "Woohoo!" she shouted and pumped her fist in mock excitement. Jeff rolled his eyes. "Ok, well if you need me, I'll be in the kitchen making us something quick for tonight."
