Logan Lerman makes an unexpected appearance in "Bullet Train" as The Son, the son of The White Death (Michael Shannon), the fearsome leader of a criminal empire in Japan. As Tangerine (Aaron Taylor-Johnson) and Lemon (Brian Tyree Henry) attempt to transport The Son back to his father, they're forced to abandon him in favour of chasing after Ladybug, who's stolen the silver briefcase full of money that they were transporting.
While the brothers attempt to track down Ladybug — who is currently fighting off The Wolf — The Hornet (Zazie Beetz), who was hired by The Prince (Joey King), walks by in her mascot costume and stabs The Son with a syringe full of Boomslang snake venom. Within a matter of seconds, the venom goes into effect, killing The Son and leaving streaks of blood dripping from his eye sockets — just like all the guests poisoned at The Wolf's wedding.
