Because she wields one, and you need to use single, 2x single and unarmed. That's the dialogue, that's the requirements. They should be mentioned in [] after Kreia refuses to train you, no?

This is unrelated to getting your lightsaber back from Atris, but I didn't want to double post and this is a bug I always encounter when leaving the Jedi Enclave as a DS character if I bring Kreia and another party member with me:
Kreia and the other party member will be standing in the courtyard, just chillin'. I don't think I can talk to Kreia (I'd have to check), but I can talk to the other party member normally. They're just not in my party and they'll both just stand there until I leave. It's not a big deal and I actually thought it was kind of funny the first time it happened. I was just wondering if anyone else encountered this problem.
