I'M DOWN. Maybe there's a cave-in and they have to work together to find an alternate route out? Like, maybe Amara needs Arid bc Arid can map their progress and ensure they don't get lost and Arid needs Amara bc Amara can use her siren fists to punch through geographical obstacles :|b

Though, we would need a reason why they don't just have Amara punch through the cave-in itself ^^;
