Science Showcase is a magazine company located in Central City.
It was raining heavily in Starling City when Barry Allen arrived and he didn't have an umbrella, thus he used the Science Showcase he brought and attempted to shield himself from the downpour. Another issue of the magazine was later seen in St. Catherine's Hospital that John Constantine was at.
Behind the scenes
- Science Showcase is likely a reference to Showcase #4, which had the first appearance of Barry Allen.
- Other than John Constantine himself, Science Showcase is the only link between and the rest of the Arrowverse.
