If Chris Harrison gave Peter some kind of upsetting update, what if it was something personal rather than connected to the show?
Maybe that’s why Bachelor Peter didn’t propose, because his lady love had to leave Australia for home?
Chris Harrison giving Peter a “heads up” sounds too casual for one of the women to be sick herself or to leave the show because she is Just Not That Into Him.
It’s more like “This could affect you if you were planning to propose to this woman, so heads up.”
