"Well," Jaina replied flatly as she dodged an attack by one vampire only to have to Force-shove another away from her as he snapped at her with his fangs, "the fact that the man with the crimson eyes who is wearing my brother's face just ordered these things to kill me tells me he isn't Jacen now."
Honestly, Jaina wasn't sure what to think. She, too, knew Jacen had been himself. He'd re-opened their twin bond and she'd felt as much herself. Granted the bond had been closed again soon after, and they'd had a falling out since that point, but he had been Jacen.
So, what had changed?
Clearly she didn't know the answer to that, and she really didn't care at this point in time either. All that mattered at the moment was finding Caedus and stopping him before he began to wreak havoc upon the people in this city. And, as she managed to kill the last of the vampires, Jaina had every intention of doing just that.
After she took care of something even more pressing, first. "Come on," she stated as she replaced her lightsaber on her hip. "We need to find your daughter, then I have to warn my Master." And not bothering to see if Tenel Ka followed, Jaina took off running at a speed (courtesy of the Force) that was so fast she was little more than a blur.
