Harry went into a booth and the 16 year old saw that it was a TIME MACHINE. He really wondered what the future looked like and-
The next thing Harry knew he couldn't breathe as he was in a sealed chamber that seemed to have no air for an instant before there was a lot of wind as air entered the room. The chamber lifted letting Harry see into the room and... It seemed like it was the basement in terms of dimensions, but a lot less cluttered. However there was some lady sitting on a chair scribbling a few things down before saying "Harry! So glad to see you mostly in one piece... Looks like you shrunk a bit and lost your clothes. Harry looked at his shrunken wiener before the lady put her lab coat around his body.
Harry asked "What happened?"
"Well... you tried the prototype of a time machine and it's been about twenty years... and you're sweet widdle sister Eriwn had to learn advanced theoretical physics while dad was in jail for being a mad scientist." Harry didn't believe this lady till he managed to do basic arithmetic and his 6 year old sister would be 26 then. "His mad science has also been adopted by many companies pushing through many innovations so things may look a little more, futuristic to you."
Harry asked "I feel small, what happened?"
"Well that time machine was just a prototype, but based on the schematics I predicted the malfunction to occur, you to teleport back here in 20 years, and for you to be fine and maybe missing a few years. It also didn't have anything to push any matter out of the way so I had to make that chamber a void or you'd have telefragged into air and that WOULD NOT have been fun for anyone."
"Is mom still around?"
"After I finished college she's been traveling mostly. She'll start coming back as soon as she heard I WAS RIGHT, but for now it's just the two of us." Erin said smirking "You know when we were kids I always wish I was the oldest child, but I guess I am now. We'll have so much to do."
