They have said that Emily Bett Rickards is still main cast, even thought it's not an uncommon trick to credit someone as such and kill them off in the opening of the next season, so maybe that will be it. Maybe she'll appear as manifestations of Oliver's grief and in flashbacks to previous seasons, so therefore she's still around without really being around.
