Only the real daughter

"What's going on?" Penny looked up at her three brothers as they stood outside her room. "Is there something I should know?"

"No — no!" Slater intoned while trying to conceal his nervousness. "We just thought that you should rest today before we start our study session!"

Skeptical, Penny squinted her eyes at Slater. Since when did this brother become so enthusiastic about their study session? Most times, she had to drag him to the library with her.

"It's nothing, Penny." Hugo smiled and hit Atlas with his elbow. "Right?"

Atlas, who couldn't even form a smile, nodded. "It's nothing. Come down when dinner is served."

Having said that, Atlas turned around to leave. Hugo offered Penny a reassuring smile before he followed Atlas. 

"You better stay there until Butler Jen calls you for dinner!" Slater pointed a finger at her, making her flinch a little. "Stay!" 

After saying that as if she was a dog, Slater jogged and followed his brothers.
