She didn't really feel like explaining her self. What was she going to say? 'I'm an alien from another world, blah blah blah.' He'd think she was crazy, not that she cared. She could drop the whole 'Supergirl' thing, but that probably wouldn't work too well. Though she might have to try later. "I defied gravity, it's pretty easy actually." and it was, it was really, really is. Why Clark still hadn't figured it out, she'd never know. Still too attached to the dream of being human, probably. Everyones life would be easier when he got over that.
Arching an eyebrow, Kara just shook her head. Right, she was white, that obviously meant she had to be human. "Clearly your mind doesn't go very far past Earth. Just because I'm white doesn't mean I'm human."
Mason, it sounded like any other name. Nothing special. He didn't appear to be lying, but this was Zod. Chances were Zod could pass any lie detector he was put up against, human and maybe even Kryptonian. There was one thing that he'd never leave behind. His tag, his Kryptonian military tag. Major Zod would never take that off. And if he did, it would be locked some place safe.
Her x-ray vision kicked into action and she began to scan the entire apartment, taking only seconds, checking to see if anything reminded her of home at all. Then she scanned 'Mason,' checking for any sort of Kryptonian object. Nothing. To anyone who didn't know her, she'd look annoyed. Andrea would probably say this was her 'you should probably run and hide if you want to live' face. Taking one step forward at a normal pace, she closed the distance between herself and Mason in blur right after. "Kara." she replied. "You better be telling the truth."
