Usually, Spencer would dislike trains. They're honestly disgusting, germs everywhere, everything sticky and dusty. But today, he had no other choice. His car was under repair and he had to visit his mother quickly.

He gave a quick awkward smile to the crew, going up to emptiest booth. You were in said booth, nose too stuck in a crossword puzzle to notice him. He look down at you, watching as your pencil paused on the piece of paper. You were stuck.

He snuck a look over the piece of paper and got a peek at the clue. He analysed it for a bit, before his mouth moved faster than his brain and he blurted out. "Caldera."

When you looked up confused, he cleared his throat. "Uhh-- two across, crimson resin below the crater.. sorry, I just.. the answer's caldera."
