The immediate danger passes, as Keith, Lance, Hunk and Pidge are free to rejoin Allura and Coran on Arus. Unfortunately, with Zarkon's threat constantly growing and the Robot Lions gone, they're still at a great disadvantage. However, Allura's recent time on Arus and with Ariella's spirit may reveal a way to restore the Lions and Voltron. They had better hurry, though, as Zarkon intends to finish the Voltron Force once and for all.
