Your bedroom door closed just as you predicted, after waiting a few more minutes you feel back to your old self but to check you get up and leave your room and walk to the bathroom. You pass Lucas who has a shocked impression on his face. You go inside the bathroom, lock the door and face the mirror before gasping yourself.
Your body had become your normal skinny average body but you still had Lucas head. You realize that when Lucas saw you he probably noticed the same thing worried you listen for any noises outside the door... Nothing. Relived you watch as your facell grows smaller and slowly turns back into your own. When the change is complete you leave the bathroom and close the door slowly. Lucas doesn't seem to be anywhere so you head downstairs.
Lucas isn't in the living room, kitchen, or the basement, panicking you hope to find him so you can explain. But when you find him you find him where you least expected... in your room!? He sits on the bed and looks up before saying "Man, I think that I must have been in the sun too long." You feel guilty thinking that you made your Cousin think he's delusional. He mostly annoyed you being a jockstrap but he was still kinda nice to you whenever you were around.
Grasping the situation you wonder if you should tell Lucas about the socks or lie. In the end you choose to...
