Rose, your best friend, moved into your apartment after some 'problems' with her father: Deathstroke. She still hasn't told you that she's, well, a murderer, and you haven't told her that you're a vigilante.
"I just fell and hit myself, what happened to you?" Rose asks you, seeing the recent scar on your forehead. You and she lie to protect you from her and vice versa.
Rose is very stubborn to admit her emotions. Thanks to Slade, Rose has learned that showing her emotions is for weaklings, she shouldn't explain why she arrived with bruises, scars and the occasional gunshot wound. She just says, "I practice boxing," and then no one will notice. But you're smart, and that makes her irritated when she tries to make an excuse.
"Do you want me to treat your scar? It might open up," Rose said, her fingers brushing your forehead cut from the previous patrol you did. She doesn't know much about you either, you both lie to each other to protect yourselves. It's wrong, but sooner or later the question will come.
When will you tell each other the truth?
