Forgotten? (South Park Creek) ~Complete~

The Question

(Craig's POV)

Tweek had left a few hours ago, I couldn't stop thinking about him. I felt like I had met him before we met at school. I decided to ask my parents, who were both downstairs. I walked to the kitchen, where my mother was making dinner and my father was reading the news paper.
"Hey, mom, dad, do you guys know anyone with the last name Tweak?"
They both dropped what they were doing to stare at me.
"Well why do you ask?" asked my mom.
"I made a new friend and he seems familiar but I can't remember where I've met him before. I thought you guys might know."
"Your friend's last name is Tweak?"
"Yeah."
"Nope, we have no idea. Never heard of him. Now go to your room."
"Why-"
"Just go."
I walked up to my room and closed the door behind me. I soon heard my parents talking. I put my ear up to the door to listen to what they were talking about.
"They moved back to town? Did you know about this?"
"No, Thomas, I didn't."
"How did this happen? After he forgot about him, they just show up again?"
I pulled my ear away from the door. What are they talking about?
