Who ever she wanted to be. OK, she got it, or she was pretty sure she did anyway. But for the most part, Kara was pretty sure she knew what was going to be happening. So she would introduce herself, but she just needed to get use to things first, and then decide who she was going to do this. She wouldn't wait to long, putting it off probably wasn't a good idea.
When she took Elaine's hand, at first, there was nothing completely different that she noticed. Then it just hit her at once. Kind of like when she first stepped out of her ship, and all of a sudden she could fly, and was so incredibly strong. The things she could hear, and see. It was, and wasn't like her powers on Earth. She had always been able to see things from afar, or hear things all over. But this was different. It was just there, and it was a bit over whelming, like when Clark had first taught her to hear. All the sounds were there. Plus, she knew things. She could feel things, she knew what was happening, and she knew when people had noticed her presence.
Her eyes had fluttered closed, if she was shifting in sizes, she wasn't aware of it quite yet, or she didn't realize she'd done it. "Different." she said, bringing her free hand to her forehead. "Kind of like when I first came out of my ship. Only it's so much...more" she didn't know if more was the best way to describe it, but it was what came to mind at firs.
