Um I've found both lol ffs got the black screen bug just now.... autosave to the rescue
My humble advice to everybody:
DON'T enter Marcus's room and start the "learning the truth quest" unless you completed the whole Emily quest (kidnapping and so on) and Frisha's quest until she becomes your lover and dumps Dave (I guess we don't want to share Frisha, don't we?).
Reason: after Mira goes to the church you have 14 days
only before Aidalin comes and the church ritual mess starts.
IMHO the plot is much better 1) when Mira becomes your lover
after you've already banged Emily AND Frisha over and over; 2) when Aidalin comes and you've already banged Natasha over and over.
I think you'd better complete the whole Church Ritual quest
after you completed Lyvia's and Imawyn's quests, too.
My 2 cents, of course.
