Needing a break from the demands on his attention and time, Garth'zel slips in. Lana and Theron know where to find him if he's actually needed for something, it's fine. The other choice of hiding spot to be undisturbed is his ship, and there's rather more going on here than there.

...Such as the man using the Force to play with kittens. Garth'zel surveys the scene before him for a moment before moving forwards. Interesting. There's definitely a sense of the Dark Side around him, but not as intense as even his own, much less many other Sith he's known. So not a Sith. Although maybe on the way there.
