The Average Geeky Nice Guy Wins

You’re starring in a new movie, Jungle Jane. The script has you land on an island, discover ancient ruins, dinosaurs, tribal natives with head hunting on their minds, and then you’re supposed to fall in love (or at least sleep with) your co-star. The only problem is, your co-star is a complete jerk. There is another guy in the film but he’s the geeky nice guy. In the script he gets killed off early, in the crash landing scene. How do you rewrite it so that the nice guy wins and the typical handsome co-star type gets blown up on the crash landing instead?
