I figured out she likes when I pick locks and choose mean, but still nice dialogue options...and she keeps yappin about helping the people of the commonwealth...except that mission where you have to get a shiskebob from some forge guys...well I saved that jake guy from killing the settler, and saved the settler, yet I didn't get a message saying she liked that...she should've slept with me on the spot for that, (you'd think?)
So far I've had 2 flirt options with her and passed both...what's it take? Are other companions this hard?
