The Season 6 finale episode, titled "Life Sentence," doesn't just share its name with one of the latest cancelled series at The CW; it also might play into the different ending Emily Bett Rickards is referring to. Oliver Queen admitted to the FBI in the penultimate episode that he is indeed the Green Arrow. That admission will likely lead to some consequences, with the most obvious being that Oliver will be sent to prison not long after Star City is free from Ricardo Diaz's grasp. That's obviously not the happy ending Arrow fans may be hoping for for after a less-than-upbeat Season 6, but would certainly allow the series to further evolve and adapt if the cast is forced to protect Star City in Season 7 with Oliver behind bars.
