I don't know why no one thought of this... But Leon was the only one wise enough to rip the healing machine out of the floor, and haul it with him out of the fire.

PS, he's talking to Sho's group :P


Side note... the water in the oasis should be fine. An oasis wouldn't form near an ocean, other wise it'd just be part of that large body of water. It'd form a bit deeper in main land, and have a dense enough surface of bedrock to isolate the water. It wouldn't have enough water to supply an entire city, but for tourism it should be fine.
