My Ultimate Eye, in a matter of seconds, calculated precisely which angles to observe puddles and windows around me to observe, indirectly, the battlefield that Aang and Hiroshi briefly ran away from before returning and, lastly, their final stand against the individuals who came after them. Every reflective surface was a camera to my Ultimate Eye and, in moments, it was able to tell me everything I needed to know about what happened to them.

Most importantly, it guided my line of sight to a single arrowhead embedded into a wall several feet away from me – deflected by Sokka’s returning, wobbling boomerang thrown while still recovering from being paralyzed. There was only one group I knew of that used arrows.

“Wait, stop,” Analay interrupted me, “You… You learned everything that happened in that fight… with puddles?”

“Well, no, I learned what happened in that fight by observing every angle of the battlefield, mathematically determining the remainder that I couldn’t see, and utilizing probabilistic formulae and understanding of weapons and tactics while only being able to look at it all through puddles, windows, and other refractive surfaces within a several hundred feet radius.” I crossed my arms and nodded, proud of myself. “Oh, and I turned my head a little to the left and saw an arrowhead, so, yeah. Take that as you will.
