I am interested in the potential interplay of Sam(uel) and Celica, both verbal and licentious. While I don't think a full Samuel route would pay off, a divergence that has Sam sticking their wick into Celica's candleholder is certainly something I like to envision.
Mind, how that can happen without Celica learning Apocalypse from pure anger and ending Samantha's world would be quite a needle to thread.
