Should we focus the next chapter on first, or does he encounter someone else who also holds a Magic Ticket?

Mateo realized the Billete wasn't a ticket for a ride; it was a permit to rewrite the route. As he gripped the pen, the golden card in his pocket grew warm and then dissolved into light. The station walls collapsed back into the familiar tiles of the Madrid Metro.

Inside, the seats weren't plastic, but velvet. The advertisements weren't for insurance, but for "Memories You Forgot to Keep" and "Directions to the Tomorrow You Actually Wanted." A conductor in a vest made of starlight tipped his cap. "Destination?" the conductor asked. "I... I was just going to the office," Mateo stammered.

The train accelerated, the tunnel walls turning into a blur of cinematic moments from Mateo’s own life—his childhood sketchbook, the piano he stopped playing, the girl he never called back in Valencia.
