Arrow Series Finale: What Does The Ending Really Mean?
5. Rene Will Succeed Quentin As Star City's Mayor
Quentin's resurrection allowed the former police captain to complete his term as Star City mayor - the one that had been robbed from him (pre-Crisis) when he was killed by Ricardo Diaz in the Season 6 finale. However, leadership of the city won't be wandering too far because taking his place as the next mayor will be none other than Wild Dog himself Rene Ramirez.
This aligns with everything we know about the future. Not only did the initial timeline have Rene becoming mayor, the character began showing interest in running early on in Season 8's present-day timeline, determined to change that dark and grim future of the Season 7 flash-forwards by only doing the good stuff.
Star City may be safe, but it's even safer now that Rene's leading it into the future - something that, according to Green Arrow and The Canaries, he does very, very well.
