Well, not all secrets were allowed to be shared with just anyone. Like this girl he just met. She could be a spy for who knows who. Even the Emperor. How could he trust it? Well, he couldn't mostly.
"Alderaan sounds pretty great." Starkiller acknowledged. "When I get back, I very much would like to visit it - if my master would allow it that is." There was hesitation, as he thought about if he would even ask, knowing how Vader would respond about all of that. With a good ole fashioned ass kicking. "I want to see snow, and mountains." Starkiller acknowledged also. "That sounds all very great!" Ultimately, the teen needed to figure out what he was supposed to do to make it happen.
While they were now sitting, Starkiller really started to dive into the snacks. Sticking to some of the sweeter snacks, Starkiller nodded. "Nope. Only time I don't have my own time to do things is when I'm training." He noted. "So, that fills a lot of time." He sighed some. It was a lot of the time, to be honest.
There was some hesitation. "Okay." Starkiller smirked. "You can't tell anyone though." He leaned over closer. "My master wants to overthrow the Emperor, and he says my power is too untrained though could be matched to his, so he's training me to help do it." There was a smile on his face while he stuffed a Twinkie in his mouth before continuing despite food being in his mouth. "I ght tu oose ah lghtserber." He told her, then swallowing the food. "Oh!" Looking around he saw a stick. Holding his hand out and really focusing, the stick levitated and floated to him.
