Can you actually get "Great Intimacy" without the freebie at the night scene with Mariah in Chapter 3 after you cleared the mines? You are locked to intimacy level 2, and I think all (or most) of the love love stats are maxed. I had the 2-3 dialogue options that lead to "good" replies with the ringing sound and I gave also gave her gifts to increase those that could be increased that way, though some gifts that were supposed to increase enjoyment and passion sometimes increased Trust, I think, instead.
