Firion was still in the process of trying to get his limbs to work again when he heard both Tifa and Tidus call for him once more. If he remembered correctly, this passage led to a fork in the tunnels, allowing him to get lost. Using the wall to keep himself steady, he continued to walk. "Down here! Stay where you are or you will lose your way."

No use in getting each other lost, after all. It wasn't long before he reached the end and it was a welcoming sight to see everyone there.
