Anakin guesses at the wince, he doesn't need the verbal confirmation. He looks down in his lap for a moment before sliding down to his feet and walking over to Garth'zel, putting his hand on Garth'zel's and patting it. "That's a lot." Of people to lose, he means, and he's trying to offer some kind of comfort for it, even if he knows there really isn't any he can. "I won't leave you." Because what does he have to offer, but a promise to not make him grieve him too?
