"I-" Oh shit. Kas isn't as fast as Sera due to the surprise, and the soldier is really yelling this time. Something about rearranging his little beast face. Rolling his eyes, the teen skids off the roof and down on the other side of the ramparts.

...then he starts running, just in case the soldier decides to finally break down and leave his post. "Catch me if you can!" he hollers, and it's definitely a challenge to both the soldier and Sera.
