Ok, you said there is one female and one male interest possible but you didn' t specify that the only female prospect was Persi. Couple that with the facts that Kora is married to Rafik and the only other female aside from Dorbi and in Calfree, there were two possible romantic female interests possible (that I've found anyway) plus the slightly dirty and lurid conversation with Dorbi in Halferville in her office, I have to ask, if you don't pursue Persi, is Dorbi a romantic option despite her insistence that any coupling is strictly for her gratification?
Seeing as she hints it pretty strongly in Caldecott and goes through with it in Calfree, i was just considering the possibilities for Caldecott.
