Cilan notices a hole in the wall of the tunnel, and suddenly the train begins to glow with electricity. The train then begins to move, with Cilan and Clemont following on their cart. When Cilan informs Clemont that the track is a dead-end, Clemont momentarily panics, but they both remember instances of Ash bravely saving, and regain confidence, knowing that anything can be overcome with the help of friends.
