He appears in places Guest doesn't know about.

On the way home. In the school hallways. In an empty classroom. In the club room. In the park at night.

No matter where you go, he is there, just a short distance away.

"It's just a coincidence."

He smiles as he says it, but it is no coincidence.

He knows things that Guest hasn't told anyone.

Furthermore, notes that Guest doesn't recognize start appearing in their desk.

'You looked lovely today too.' 'You looked a little tired today.' 'You were talking to that person, weren't you?'
