Be warned! If you're not completely caught up with Arrow yet, there will be some spoilers discussed below, so be sure to read on at your own risk. The hit CW series is about to go back into production for Season 4, after the Season 3 finale left fans with a number of questions about how the show will move forward this fall. This is your last chance to avoid any spoilers, so stop reading now!

Last month's finale showed Oliver Queen (Stephen Amell) leaving his costumed vigilante identity behind, as he fled Starling City with Felicity Smoak (Emily Bett Rickards). The big question is how can a show called Arrow exist without the title character? Of course, the show's producers have had similar challenges in the past, when Oliver was seemingly "killed" by Ra's al Ghul (Matthew Nable) in the midseason finale, although he eventually survived. The actor took to his Twitter page this morning for a fan Q&A, where he was asked to describe the Season 4 premiere in just three words. His response was, "What's wrong Speedy?" Is this what brings him home?

The actor is referencing Willa Holland's character Thea Queen, who took on her own costumed superhero persona dubbed Speedy in the Season 3 finale. Before that, though, she was also killed by Ra's al Ghul, before being brought back to life in the Lazarus Pit. It's possible that Thea may be suffering from some resurrection side effects, but Stephen Amell's three-word response is too vague to discern any specifics, and he doesn't address if Oliver has truly left Starling City for good or not.

In related news, Arrow executive producer Marc Guggenheim revealed the title page for the Season 4 premiere script, although the title itself was obscured by a pen. We do know that Marc Guggenheim co-wrote the season premiere script with Wendy Mericle, based on a story by Greg Berlanti and Beth Schwartz, with Thor Freudenthal directing. What do you think about these Season 4 details? While we wait for more specifics to come in, check out Stephen Amell and Marc Guggenheim's tweets below.
