Angel had originally guessed that the clue here might be some special change on the extraordinary side, visible only by activating "energy vision" at close range.
That was precisely why the God's-eye view was useless here; he had to come in person to find the clue.
But after the fruitless search just now, his thinking had begun to change.
Perhaps the clue here was not the kind of hidden clue he had imagined, but one that required "puzzle-solving" and "deduction."

As for everyone else, they might not even be able to find where the question itself was. Angel was a perfect example—he had searched this place over and over countless times, yet had found nothing unusual.
Fortunately, Zuniga had arrived now. With his help, perhaps they might have a chance of finding the clue.
