Finally, they managed to do something for Riona. Under Emperor Kaan's command—which Thorin and Puck grumpily obeyed, since the emperor might be her only chance at survival—they moved Riona to her room.
Then, despite Thorin and Puck's obvious reluctance, they left her alone with the emperor. For some annoyingly shady reason, he insisted no one could be present while he performed the magic to cure her.
Naturally, Thorin took this as well as you'd expect.
Thorin flat-out refused to leave. It wasn't until Puck, clearly fed up with his dramatics, grabbed him and physically dragged him out that they got anywhere. And even then, Thorin fought like his life depended on it.
Meanwhile, Riona was over there struggling to breathe, which really should've been the focus of the moment, but no—Thorin was too busy being the most protective boyfriend of the year.
