Ok so on my 3rd play through of this DLC I couldn't help but notice how in every way I played it I could not get not to be hostile towards me after meeting up with her in the hotel, I did all of the requirements for the skill checks and nothing works! I even didn't force her to go down the elevator. The only check I didn't complete was the 70 med one before entering the Sierra Madre Casino.
How exactly do you access the other endings for her?
