Following the supposed death of Ray Palmer at the end of Season 3, this current season opened with Starling City being renamed to Star City in Rays memory. With that said, it was all a bit odd to see that the citys hospital, where Felicity Smoak is holed up, still being known as Starling Hospital. Whether this was an oversight from the show or not, or maybe its a case of the hospital favouring tradition and recognizing the citys roots, who knows. Either way, it just stood as a little puzzling to see the Starling name come back into play.
