Luke found himself wondering if she was related to the Emperor in some way but she didn't seem to be. From what he could sense, she was being honest with him and not hiding anything so she would have told him if that were the case. Her words took a moment to sink it and then Luke looked at her in surprise.
"You were looking for me, weren't you? That's how you knew me and I don't know you." It didn't take much to guess what she'd been planning to do when she found him. "I hope you aren't planning on actually carrying that mission out since I'd really rather not die yet and not in this place." He was pretty sure that if she'd wanted to kill him, she already would have, it wouldn't be hard.
