Welp ... we know for sure that rapist-kun is now an antagonist. That little turd will show up later to cause some problem with the main group. Oh, and his rapey tendencies will have multiplied 10 fold by then, which probably means kidnapping and some BDSM thrown in for good measure. Plus he got his arm broken ... oh yeah ... they are setting him up to be the foil that fucks everything up near the end. I would love it if he ran into the natives and they took him to some cave where THEY played poke a hole with him ... but that would be too cruel ... maybe even for him.
