Rastun agrees with Brainwave and immediately speeds out towards the cave's exit. He dodges the falling stalactites in his way while maintaining his fastest possible speed. After several minutes of constant evasion, he finally makes it out of the cavern. As for his two acquaintances, Rastun assumes they're right behind him. They should be fast enough to escape a cave-in and he doubted they'd want to suffer the indignity of being literally carried by him. Presumably, there's nothing left in Carbombya worth investigating. Leaving this nonsensical nation can only be a positive step towards their goal.
