Lily, ecstatic at her newfound ability and her power to control her brother, lets out a barely-concealed squeal of glee. She can barely contain herself; after all, she's already come this far! The more rational part of her, however, was more cautious. She'd managed to hypnotize her brother pretty easily, but she didn't know how far she would be able to take it. One wrong suggestion could make all of this fall down around her. For now, the best idea would be to let her brother relax and tighten her control, slowly but surely.
"All right, big brother," Lily begins. "I want you to remember this state of being so relaxed, so open, so completely trusting of your sister. When I snap my fingers and say 'relax for me', you will return to this state, so long as you would not be in danger if you did so. When I snap my fingers and say 'wake for me', you will wake up, completely unaware that you were ever relaxed. Do you understand?"
"Yes," Sam breathed. Lily let out a small sigh of relief before continuing. "Now, Sam, you trust your sister completely. You feel so incredibly at ease when she is around, as though her very presence relaxes you. You feel as though you can tell her anything, and you respect her advice and opinions. Do you understand?"
"Yes," comes the response again. Lily smiles. "All right." She snaps her fingers. "Wake for me."
Sam blinks, his stance and eyes returning to what they were like before Lily had hypnotized him. He looks over at his sister, and already, his look is much softer than it was before. "Is that it?" He asks his sister, in a much kinder tone than before. "I didn't even do anything."
"Nope! That's all," Lily replied joyfully, getting out of her seat. "Thank you!"
"You're welcome," Sam replied quietly, even smiling a bit. "Good luck on your assignment."
"Thanks!" Lily leaves the room, shutting the door behind her. She immediately presses herself against the wall, happy that it had worked and in awe of the power she now held. She considers her options.
