Us and Them

"They have it easy, don't they?" -Six
"They? Why are you speaking like I'm one of you?" -Baltar

This whole scene was quite interesting. Baltar is really starting to become suspicious of his relationship with Six, of his own humanity. Everything Six keeps saying just doesn't add up anymore. Does she want him to find out he's a Cylon? Or is she simply messing up by saying, "we, them, us" and he's still not meant to know?
