I can't seem to get this scene to happen, I can't seem to get Urta's drinking scene anymore, I can't get any scene where I just talk to her. Every time I approach Urta at the bar, it just asks for sex, either back at her place or stuff behind the bar. Is there a specific time at the bar where she's drunk? I told her earlier about drinking, to just be herself....does she not drink anymore?
EDIT: I missed one line in the wiki. She has to have her lust sated in order to talk normally at the next encounter. I was avoiding sex with her cause I didn't want her getting pregnant which causes her to not drink. Instead I chose one of the receiving options and then was able to tell her to drink a lot at the very next encounter. Then the third encounter I talked to kath, said to drink, saw urta, and yay threesome!
