>MatPats POV<
I finished recording and walked out of my recording closet. I heard the TV in the living room. I walked out to see Y/N and her friend on the couch laughing and watching something. It sounded like my voice, and I chuckled. Y/N turned around to the sound of my laugh, her friend following. Her friend looked starstruck. "Hey, I'm Ma-" I said, seeing they were watching game theory.
"MATPAT?!" Her friend screamed, causing her to laugh.
"Cass -" She laughed. Wait, Cass? That's short for Cassidy. That name... She had black hair yellow beads holding up two ponytails... could she be... I shook my head.
"Nice to meet you." I said, trying not to look nervous.
"Nice to meet you too! I'm Cassidy!" Y/N's friend said. I remembered I had a GTlive that Y/N was gonna be on.
"Hey, N/N (Nickname), do you still wanna be on GTlive?" I ask.
"Oh, yeah! Uh, Cass, you gotta go.. sorry. See you tomorrow at school!" Y/N said, waving to Cassidy. I got everything set up for the video.
"Hello Internet, welcome to GT-not-live! Today, we have a special guest, Y/N, my daughter!" I say, Y/N walks out and sits next to me on the couch.
"Hello Internet! My name is Y/N, and I do a lot of things with my wonderful dad." Y/N said, smiling.
"Today, we'll be checking the reddit! Our new channel came out two days ago, and we want to see what the reddit has gone since then." I say.
