If you were romancing someone else you might not get the movie,because after you rescue her she says I love you,so if she's not your love life she won't say it.....
I just finished playing with the Tashia mod and thought it was better than all the others but I'm not sure I got all the love talks,my last one was #1026237 just before the final chapter in T.O.B. We never even slept together..wish there was a walkthrough of all the places you have to be to make the love talk happen..If any one knows of this please let me know,thanks
