Despite what his upbringing might suggest, Tenn was not typically one to break the rules. A bit rebellious maybe, but going out of his way to sneak away from the temple for a night? That was a bit beyond his typical MO. Whatever misgivings he might still have about the Jedi, they did give him shelter, food, and companionship.
Even if he was still willingly neglecting that last one.
The point being, why would he ever want to jeopardize that? And the answer to that point being, he couldn't ignore every problem. Especially not the ones happening beneath his very feet. Despite Coruscant's gilded surface, its underworld was home to some of the worst crime the galaxy had to offer. Tenn should know, since he spent several years slumming it a few thousand levels below.
The padawan crept through the Temple halls with practiced ease. One didn't survive the urchin lifestyle without knowing how to stay light on your feet. Shep stalked closely beside him, a faint orange glow casting off the charhound's eyes and striping. Not the most pragmatic evolutionary trait for stealth, but being able to belch fire was a neat enough tradeoff. Even less helpful for their purposes, was when Shep started growling, "Shh…" Tenn hissed, trying to put a quick stop to it. No use. The dog had smelled someone nearby, and bolted down the hall to investigate, "No! Bad Shep-!" He took off after, rounding the corner to see Shep rolling playfully on the floor, in front of one of Tenn's fellow students. So much for leaving undetected. "Uhh... Sorry." He rubbed his neck awkwardly.
