Bernie is a young man who used to hang out at Bernard's newsstand sitting on a spark hydrant to warm his back while reading a comic book, "Marooned" (an issue of the Tales of the Black Freighter series). He frequently goes back to the stand to continue the story.
Bernard did not like Bernie at first for reading comics for free, and refused to give him his cap when it rained; but as the nuclear war threat emerged, his emotions started to warm. Bernie complained that the first issue ends abruptly and that he will have to wait for next month and refused to pay for it, but Bernard gave him the comic book, as well as his cap to protect him from the rain, telling him to be good to his mother.
Bernie returned later on October 21 reading the first issue. He complained when a Pyramid Deliveries truck splashed water on him, and the driver scolded him for being in the way to the hydrant. On October 28, Bernie is seen disposing a wrap paper of Mmeltdowns in the trash bin of the Seventh.
As days pass, Bernie goes back to the stand to read more of the Tales of the Black Freighter series. Finishing the story, he didn't like it and gave it back to Bernard which angered him a little since he was being nice to Bernie. He said that all the time they saw each other he never actually got his name, and so Bernie told him. Bernard was surprised that both of them have the same name, but Bernie didn't care too much since it's a common name. As they are having a conversation the alien monster Adrian Veidt teleported from inside the Institute for Extraspatial Studies. In their final moments, Bernard attempted to shield Bernie from the teleportation blast, but to no avail. The monster's psychic blast killed three million people in New York City including Bernie.
While too young, Bernie is seen smoking hand-rolled cigarettes. He is audacious because not only he is reading for free, blocking access to the spark hydrant, but also demands from Bernard to give him his hat when it's raining, complains that the comic he is reading for free is a rip-off, and complains when passing cars splash water on him or when Bernard is ranting.
