"Heh... my stupid brother won't know what going to happen to him.", Yumiko says to herself and waves to her new brother.
Her brother see hers and waves back, and says his goodbyes to his friends. He heads towards the front door and puts his hand on the door knob. Instantly, he jumps back and everyone could here him yell, "What the fuck!". Yumiko giggles as she runs downstairs and removes the trap she had laid on the front door, just to have the door slam on her face as her brother opened it.

A switch inside of Yumiko's brain switched and set her on a path that happened once before.
"Man, why did the door handle shock me?", Yumiko's brother said.
Meanwhile, Yumiko had gone to the room under the staircase and brought out a cattle prod and taser. As her brother faced away from her, she shot him with the taser. Putting the electrodes right on his neck, sending him right to the floor.
"dId you LIke sLamMinG tHE doOr On YOuR SistEr'S fAce?", Yumiko said with an evil grin on her face.
Her brother couldn't speak as he watched Yumiko walk right up to where he fell onto the ground with the cattle prod raised in her hand.
"It DoeSN't mAtTEr. WaNNa KnOw whY? WaNNa? WaNNa?", Yumiko giggled.
Her brother forced out a hoarse "Why?", as he laid on the ground in the fetal position.
"beCAusE We'RE goiNG tO Be PlaYInG a GaME!", Yumiko said as she clapped her hands together. "GeT It rIgHT aNd I'Ll leT YoU rESt.", with a smile on her face.
"qUEsTioN oNe! wHO is My bROtHeR?", Yumiko asked with happiness laced in her voice.
"Me?", her brother gasped out.
"WRONG!", Yumiko screams as she slams the cattle prod into her brother's exposed side, making him convulse uncontrollably. After a couple seconds, she raises back up the prod and walks around to the other side of her brother laying on the ground, twitching. Yumiko squats down and looks into her brother's terror stricken face closely and asks the second question.
"Who Is tHE BoSS oF thIs HoUSe?"
"You are.", her brother answers with tears filling his eyes.
"GoOd.", Yumiko says as she goes back to the room and retrieves some of the tranquilizer she had used in the food earlier that day. She gets one of the syringes and withdraws a hefty amount of the tranquilizer and walks back over to her brother still on the floor in between the hallway and the living room.
"thIs WoN'T hurT a BiT.", Yumiko said as she sticks the needle into her brother's side, and sends him off to a deep slumber that won't end until next morning.
Yumiko starts dragging her brother upstairs as she cleans up everything that had happened before her new parents get home. And sometime during all of that cleaning, the switch in her head went back to normal.
