Like a restless mother bird that searched for food to feed its hatchlings no matter if there's rainstorm or snow, Rex is currently sitting on the throne in the great hall while applying ointment to the severe wounds he suffered from the first ascension trial.
It's true that he's weakened right now, the external foreign Origin energy is messing with his body.
But there's no time to waste for him to heal first for a couple of days before dealing with the problems. For all he knows, Kyran might be going through a horrendous moment right now that simply can't be let on for longer.
Rex is waiting for Flunra and Evelyn that are going to accompany him.
Although Adhara is still unconscious inside the castle, he simply has no other choice but to trust Gistella in protecting her. With the Ice and Snow Full Moon still activated, Rex still needs Evelyn's presence to block the direct exposure that is freezing for him.
