Well, she didn't comment about knowing the things he'd done. So either she didn't know, or she was wanting to give him a chance to prove he changed. And she was agreeing to being taught by him.

And what makes you think I need a pilot?
The former apprentice to Darth Vader looked down at Leia as they walked. "So...do you have a lightsaber? I could also teach you how to fight."
