At the end of "Volkan Inferno," Klonoa finds himself on a bridge, and he's cornered by an oncoming train and the returning Biskarsh. At the very last second, Klonoa ducks beneath the rails and hangs onto the bridge for dear life as Biskarsh and the Train collide. The accident ends up taking out Biskarsh for good, and Klonoa gets out of the incident completely unscathed, making for a cathartic end to one of the most hectic levels in the game.
Leorina delivers a brutal"Reason You Suck" Speech to the King of Sorrow just before his second phase. She essentially calls him out for his self-isolation, which not only worsened his depression but twisted his worldview into something lethally selfish. She concludes by urging Klonoa to finally knock some sense into his majesty. As sympathetic as the King is, he really needed the reality check.
"Don't flatter yourself! YOU isolated yourself from the world, thinking that you're the only one who's sad! You make me sick! You make me... you make me want to cry! Klonoa! He's a lump of pure sorrow! Show him the Elements from the other Kingdoms. Tranquility... Joy... Discord... and Indecision! Make him remember, what the real world is about!"
Klonoa 2: Dream Champ Tournament
It's rather subtle, but Dream Champ Tournament and Dream Traveller of Noctis Sol both return the leaf to Lolo's hat, implying that she earned her Priestess status legitimately. It seems the promise she made at the end of Lunatea's Veil came to fruition.
