Truth was, Katherine had changed. So much. Lawrence had been hell for her at first, shunned and slighted by word of mouth of others from home, she didn't even have her game of playing Elena at her disposal because the doppleganger was already there. Her team up with Moriarty, which seemed so very long ago now, had certainly not helped.
But things were so different now, and she understood it was hard for people from home to wrap their minds around Katherine Pierce not being the same cutthroat psycho bitch vampire they knew from Mystic Falls, so she never held it against them when they showed up. She had simply taken to proving it, by her actions. They meant more than her words anyway.
"Hey," she said in greeting when Elena walked up to the bar to order something. Katherine had been a few minutes early and already had her drink in hand. She could only imagine how much more awkward this was for Elena than it was for her.
