Infiltrated in the Past

Day 1 - After chemistry class.

Clara: Did you see what Noah did today in chemistry class?

Luke: The girl who looks like she came straight out of a robot commercial? Haha, what happened?

Matthew: She corrected the teacher. And she was right.

Luke: She corrected 'Professor Chlorine'? That guy is scary! How did she survive?

Clara: It wasn’t normal. The teacher said something about chemical reactions, and Noah said, 'In 2045, those formulas will be obsolete because a new compound will be discovered.'

Matthew: 2045?

Luke: It must have been a joke. Or the girl thinks she’s Nostradamus.

Clara: It wasn’t a joke. She said it super seriously, like she was reading from a book. Then she went quiet.

Matthew: Wait... what if she’s one of those weirdos who believe in conspiracy theories?

Clara: Or... what if she actually knows something we don’t?

Luke: Sure, and I bet he also knows the next winning lottery number. Clara, you're so dramatic!

Matthew: No, wait. Now that I think about it, didn’t you notice he never uses a phone? And that he seems like he doesn’t understand how normal things work?

Clara: Exactly. Yesterday he didn’t know what a meme was.

Luke: He doesn’t know what a meme is? Now I’m really worried.

Matthew: This isn’t normal. We need to find out more.

Two days later - Break time.

Luke: I just saw him. He was in the yard, staring at the sky like he was waiting for someone to come down in a UFO.

Clara: That just makes him even weirder.

Matthew: I’m starting to think there’s really something going on with him. Today he asked me what 'streaming' means.

Luke: This is getting weirder and weirder! Streaming is like... basic. Everyone knows what it is.

Clara: If he doesn’t know that, maybe he’s from somewhere without internet.

Matthew: Or... from some time.

That same night.

Matthew: Guys, I was watching him closely today. There’s definitely something strange about Noah.
