Because snakes are really interesting, and Sephiroth's nowhere near as concerned as he should be about this. "I don't know. Maybe it's just called snake island, and there's no snakes and it doesn't even look like one."

There's snakes. There's snakes, and they might see both teenagers as food, getting OFF at the trolley stop to investigate, knowing it's a six hour wait to get another ride.. would probably be a very bad idea. "We should find out. Bring back a snake."
