Crux would really want a chance to go to Siesta with Blaze! Even if it wasn’t the original island, the two of them never got the chance to go out there together and just take in not only the Obsidian festival, but just the entire ambiance of the world not in trouble, everything just the right amount of energetic.

As for what they’d do, I think aside from the appeal of the obsidian festival itself (Blaze would probably support AUS and Crux would be on team DDD, whoever could garner up more support by the end would treat the other to a very nice dinner) the two of them would take a lot of time to swim around, hike through the more natural areas of the island, and at the end of the day they’d probably swim out decently far, have Crux make a little ice patch for them, and just float out on that and watch the stars together, the vacation they missed once, and wouldn’t wanna miss ever again.
