[Arrow season 3 SPOILERS ahead.]
Throughout its third season, The CW's Arrow explored some of the darkest parts of Oliver Queen's (Stephen Amell) identity, before ending on a surprisingly optimistic note. Oliver retired his Arrow persona (for now) and drove off into the sunset with Felicity Smoak (Emily Bett Rickards), choosing love over his crusade. Starling City hasn't been left unprotected, though, as Thea (Willa Holland) is now the vigilante Speedy and Diggle (David Ramsay) is set to don a mask of his own, in order to help carry on Oliver's mission.
That said, the titular character isn't likely to stay away from trouble for long. Oliver may have hung up his Arrow hood for the time being, but that doesn't mean he won't be returning to Starling City as Green Arrow down the line. The character is more of a swashbuckler than a brooder and would fit in better with next season's lighter tone, as it were.
Amell took to Twitter today and offered a hint at what could bring Oliver back to Starling next season. Specifically, during a Twitter Q&A, Amell was asked to describe the season 4 premiere in only three words. His reply was simply "What's wrong Speedy?" That wonderfully cryptic response opens the floodgate for speculation about next season.
Fans of the series will recall that Thea was killed by Ra's al Ghul toward the end of Arrow season three. That event served as the catalyst that brought Oliver into the league and led to his showdown with the Demon's Head, eventually. Thea was resurrected using the Lazarus Pit, despite Malcolm Merlyn's warning that there would be side effects and consequences for its use.
Thea temporarily suffered from amnesia, but otherwise the pit hasn't had much of an effect on her. Her resurrection was too pivotal a plot point to be swept away that easily. No, the side effects that Merlyn warned about are likely going to crop up in Arrow season four, starting in the premiere. The Lazarus Pit in the comics causes temporary insanity, so it's not much of a stretch to assume Speedy could turn on her allies (if only temporarily) and need to be stopped.
This would open the doors for Oliver to return to Starling City, as there's no chance he'd let Thea come to harm. It's a way to organically reintroduce Oliver to the city without compromising his decision at the end of Arrow season three. That said, Amell's tweet could just as easily refer to Thea coping with her brother's absence or struggling to fill his shoes as a vigilante.
