You're ready to tear your fucking hair out.
"Fuck off, Lalonde," you growl, "I'm not projecting anything onto anyone." You slump in your seat and cross your arms, glaring at her from across the table. The fact that she would even consider suggesting such a thing offends you.
And now she's just giving you that coy smile like she's got this stupid idea of some stupid thing she's figured out and you really wish you'd never come to her about this. "Karkat," she begins, as if you weren't already paying attention, "are you telling me that you don't spend sleepless nights alone in your room, lamenting your quote-unquote 'failures'?"
You frown and blush slightly, averting your gaze. "Of course not," you mumble, even though you know that she knows you're lying. She's Rose Lalonde; of course she knows.
"I see," she says with a nod, "then I suppose Kanaya's worries are unwarranted, and you've finally managed to break a habit that you've had for sweeps?"
She's staring you down, and now you're sure that you absolutely regret ever even considering coming to her with this; the hint of an idea that something good could still come out of this is gone now. "Yes," you lie again. If you open up too much to Rose, you won't be able to get her off of your back…well, ever. You'd rather avoid that road. "Look, if you don't think there's a problem, I'll just fucking leave. Sorry for wasting your time; I just thought you would care a little bit more."
Rose raises an eyebrow, but otherwise her expression doesn't change. "The possibility that something could be wrong with my brother is absolutely something that I care about, Karkat," she says, and god damn if you wish she couldn't just say what she has to say without making it so unnecessarily wordy. "But as I've said before, if something were wrong with Dave, he would want to speak with me about it. That's the way it's always been with the two of us. Okay?" Her smile becomes more genuine, and you feel like it's another example of her strange sense of sarcasm. "There's nothing to worry about."
You scoff. "I wasn't worried. I just thought you would be." You stand up and shove the chair back under the table. "I'll be in my block if you need me."
You wonder if she knows that you plan to scream into a pillow once you get there.
