Here you were, naked, scared, and slightly drunk. You just had sex with you own future daughter! you couldn't even think of what to do with her rambling on how she had screwed up the timeline, and how she would never be able to face her parents again, and then she broke down crying again, realising she might be stuck here forever, especially since you couldn't remember where the lamp was, if it would even work. You would have probably done the same if you had been more sober, but instead, you listened to your tired, drunk, and still hung over brain, and ulled her onto the bed and kissed her, until the kiss turned into sex.
