Ever heard of the term "suspension of disbelief"?
It's a term that describes how we, as those being entertained, are willing to embrace certain (otherwise) ridiculous or improbable "facts" about the piece of entertainment we are consuming. For example, we suspend our disbelief that aliens exist, and so it allows us to enjoy watching the tales of Superman, as well as various other superheroes.
However, everything has to follow some internal logic - it needs to be consistent, in order for the suspension to maintain it's credibility. For example, if Superman got shot & was killed by an ordinary crossbow at the end of Man of Steel, that would be ridiculous! But not because of the absurdity of an alien getting killed by a medieval weapon, but because the movie's internal logic established Superman as bulletproof.
See the point & effect of suspension of disbelief?
Nicole still had a long way to go before she should've been willing to elope with MC to some god-forsaken jungle in the middle of nowhere, just to have a sexual relationship with him. 5 days is not enough to corrupt a mature woman via blackmail into becoming someone's cock-sleeve. In this case, Superman was shot & killed with a crossbow at the end.
