After seeing that "who is left" (herobrine victims) image and considering there hasn't been any bestiality in a long time.
I hope a herobrine x Alex scene envolves "death by snoo snoo" with bestiality,
like a sparky level up where he gets a massive deadly monster horse dong and he busts into her house (thinking time for round two) while she is sleeping (inflation explosion),
or introduce wolves, have her get gangbanged and then eaten alive by the wolves.
The death scenes as of yet haven't been very sexual though have they, so that probably won't happen, but its food for thought. (i'd honestly prefer normal bestiality. maybe alex finds out about the golden apple and sics sparky on the witch as horny revenge or something)
Regardless, herobrine is best girl and my dream couple is herobrine x sparky (would much rather have this bestiality than what i mentioned above), that would make this game for me.
