Arrow Season 8 Premiere: 12 Easter Eggs & References You Missed In 'Starling City'
3. 10 Steps Ahead Of Him
'Starling City' was full of references to Season 1, but that wasn't the only season that got a shoutout as, through the introduction of Earth-2's Adrian Chase, we couldn't help but cast our minds back to Season 5 and how the Earth-1 version, Prometheus, single-handedly became one of the Arrowverse's best villains.
Clearly the writers couldn't help but recall it either as Oliver and Adrian's constant bickering produced some hilarious moments, but none of them were better than this one.
Upon realizing that Tommy was pulling off his very own Undertaking, Oliver used his knowledge to deduce that it would take place in the location that Thea died. This revelation resulted in Chase smartly asking him if he was psychic, to which Oliver replied "Maybe I'm just 10 steps ahead of you!" - undoubtedly a sarcastic reference to the fact that Prometheus took great pleasure in reminding Oliver that he was always 10 steps ahead of him throughout Season 5.
