What does your OC lie about?
In what way(s) is your OC bad at life?
What's the fatal flaw in your OC's relationship(s)? What could destroy those relationships?
Why thank you for asking.
I'm going to talk about Freddy and Leo from my cop/con artist romystery because that's who I currently have brainworms about
What does your OC lie about?
Freddy: Freddy is much more likely to stay quiet and let people make assumptions about him than he is to actively lie. When pushed, he's almost uncomfortably blunt. The exception is when his mostly-dormant sense of justice is triggered, and even then, he mostly lies by omission, because he's just not good at it. The only times he really lies for personal gain is to get out of things like work and seeing family when he's too burnt out and depressed, so he can stay home with Ellie (his scruffy lab/mutt).
Leo: Everything. He sees lying as a tool, one of his most useful, and he lies to protect himself, and he doesn't see anything wrong with it. He spins stories for his marks - stories of excitement and danger where they get to be the clever, intrepid heroes - but they're ultimately safe, because if the "venture" doesn't pay out, all they've lost is some time and some money, and in exchange he's taken them on a lovely little ride. (He also lies to himself.) He lies to the world, including his friends-who-are-family, putting on a fun, flirty, exaggeratedly fruity persona that masks his true vulnerability and loneliness. He lies about lying, pretending that the life he lives is one of romance and glamour instead of brutal marginalization and desperation. And he does everything he can to hide the fact that he has epilepsy, because he hates losing control of himself and how when the mask slips all of his vulnerabilities come tumbling out.
In what way(s) is your OC bad at life?
Freddy: so much. Just off the top of my head: talking to people, expressing his feelings, standing up for himself, being happy. He looks like someone who has his life more or less together: he has a stable job, a small house he's making mortgage payments on, a dog. But it's a life he doesn't even like, and he has never once taken a single step to make it better for himself. He doesn't fight for the chance to see his kid (who lives with his ex). He stays in a job that traumatizes him, around horrible people who bully him. He just keeps his head down and exists, miserably.
Leo: Leo has little idea of what current events are going on around him or what normal life for real people is like, and he doesn't see much value in finding out. He sees himself as outside of real peoples' lives, and he learns just enough about them to manipulate them into giving him what he needs to get by. And he's fine with that (or so he would say).
What's the fatal flaw in your OC's relationship(s)? What could destroy those relationships?
Freddy: his abysmal self-image and his complacency. The way he just takes whatever is given to him, brutally unfair or not, and lets good things go without fighting for them, and puts up with things that are absolutely not okay. The thing most likely to destroy his relationships - the thing that did destroy his relationship with his ex - is him just not being able or not choosing to speak up about what he feels, good or bad or otherwise. (And, of course, the fact that he's a fucking cop.)
Leo: needing to be in control, needing to be steering the ship whether that puts him in a more closed-off provider role or a topping-from-the-bottom role full of faked vulnerability. Being unable to get real and let his walls down, always on, always a step ahead trying to manipulate things in his favor, always calculating his reactions. He would say that the thing most likely to destroy his relationships would be the exhausting, terrifying, ever-present possibility of slipping up, but actually he's doing it himself by refusing to ever be ugly and vulnerable and present as himself. (And there's his plan to be in the wind the second he can figure out how to get the fucking ankle monitor off.)
