Okay, here's a convention of books and movies that I'm freakin' sick of... we've all seen scenes that go something like this:
MAIN PERSON- Whew! I rescued you from the Evil Bad Guy and foiled the evil plot that occurred about 5/8ths through the story, centering on the fact that I care about you deeply, though I've never said it out loud!
MAIN PERSON'S LOVE INTEREST- You sure did rescue me! I can say it out loud now: I love you. Kiss me and let us face the Evil Bad Guy... together!... as a couple in mad, passionate love!
MAIN PERSON- ......... no! It can never be! If the Evil Bad Guy knew how I felt, he'd use you against me! Therefore, despite the fact that I'm clearly in love with you and you're clearly in love with me, AND the fact that the Evil Bad Guy is savvy enough to realize it, even before I did, I'm going to walk away and lament my lot in life until I find the inner strength to blah blah blah blah blah...
I'm sick of it.
My question is this- if the bad guy gets the not-significant-other-cause-they're-not-dating and kills them, is that gonna make it less painful? Has there ever been a protagonist going "Well, thank god we stopped seeing each other and had never been officially dating, otherwise their death would send me into a downward spiral of guilt and self-loathing!"
Furthermore, has there ever been a bad guy who's gone "Bwahahaha! They love each other! Excellent! They shall make wonderful bait for this trap full of starving, crazed weasels with... wait, what?... they've decided not to date? Shit. Did they change their FB relationship status? If they haven't, we've still got... Oh. Shit... Alright... Hey, hey guys! Call it off, okay? New plan. They're not dating anymore!"
I didn't think so.
