I hate when they toss in some rando who acts like no one in his position would act just to create some drama. Spend some time setting up why he would let his emotions override all reason. If the setup isn't worth the time than neither is the payoff lacking any setup.
Like most dramas, the conflict that would easily be solved if people just F#$@ING talked to each other. So of course the most logical thing to do is not that. There wouldn't be a story otherwise.
