There are questions about her being 15, but she was certainly 16 when Clemens took her on unaccompanied vacations. I am almost 100% certain Roger did NOT wait 2+ years to get intimate with her. I'm all for believing the woman, but when she really liked Roger,felt is was consenual, and he was paying her large sums of money, one can understand her not being fully forthright.
Clemens clearly took advantage of her naivety and her vulnerable/fragile circumstances. She ended up getting hooked on drugs (maybe using some of Roger's money to buy them) and ultimately committed suicide years later. She was obviously a troubled girl from the start, and the community down here in Sugar Land pretty much all agree that he is a scumbag and did much worse than what came out. I know you can't believe rumors, but there is just too much evidence for me to think nothing happened until she was 18.
