Can being a creation of a higher power/dream boy count for seeing Borderlines in this instance!? Let's say it's that, or even Gibbs (not a human at all) squeaking and spotting the new lightshow, directing Tidus. Either way the effort helps, and the pair - being pushed by the wind, but resilient - rush towards it, witnessing it growing brighter.

When Tidus sees the figure, small, a familiar bed of hair along with that voice, he starts to realise-

"Hey, hey-! Romeo?!"

But just as Tidus's voice calls for Romeo, a hand grabs for the boy from behind - the rain itself, trying to stop Romeo from being found.
