well i disagree
i had this finishing sequence with vico and you need to show her that it is nice to just sleep together without sex,
after the night she will just said, oooh is it time to stand up now i really liked it and so on
but i guess with finish u mean the usuall way, llolth sends her minions and she is getting shaken so she is quitting and you begged her to stay even without ur romance.
well the thing i could ask u is, do u have the latest patch ?
i just played a game with dating vico and i went through everything even the vampirism act and the dialoge startet right at saradush
if ur curious i could give u my savegame though.
so you could test that u maybe screwd ur romance in soa
just pm me
