Potato is momentarily blinded by the gleam and before he can respond to Nivalia, who he noticed had put her snake away, they reveal themselves to be guards in rather ineffective golden armor. Seriously, who decided to make golden armor? Gold isn't useful for more than lame'. Gold breaks if somepony so much as throws a potato at it. The whole day/night thing between day and night guards is fine, but giving them heavy, yet soft armor that cost as much as a house isn't a great idea. Guards are stupid.
Potato blatantly ignores the command of "Halt!", the vegetable themed superhero not listening to ponies who wear useless yellow rocks as armor, because again, its stressed that guards are stupid. Potato trots up behind the guard that's behind the mysterious figure. The guards are then flung willy nilly, and the mysterious figure also jumps down. Potato prepares to follow, yelling out at Nivalia "Come on! We need to jump down after him!" because jumping from a the roof of a house is a good idea.
