When she got the answer that it was Elena, she reached her hand out to help the girl up. Had it been Katherine, she wouldn't have been eager to help her.
With the rumors she had heard about the girl and what she had just experienced with the vampire, it wouldn't be a wise idea for her to help the supposedly evil vampire that night. It was better to be safe than sorry. As far as she knew, Elena was on the side of good so it wouldn't hurt her to help the girl out. After she blasted her into the air, it was the least she could do.
"It's called leptokinesis" She replied as she pulled the girl up. She gave her and apologetic smile once she was standing then she went on to explain what happened. "Or in layman's terms, molecular manipulation" She would explain it in more detail but she was more concerned about the well fair of the girl infront of her. "Are you okay? I'm so sorry. I was on edge from a vampire trying to attack and I wasn't thinking clearly. You're not too hurt are you?"
