[ that's just it. rose has gotten used to dave telling her the truth, and telling her how he feels. he told her about bro, so she's begun to expect him to not... do this, right here, what he is doing. she expects him to be honest with her, at the least, or at least not lie to her face. even if he avoided talking to karkat thus far, he always told her about his feelings and this... settled those feelings, right? his issue was that he wanted to be public with karkat, karkat agreed to be public, dave agreed to accept that? that's what she thinks has ocurred here, and that sounds like a job well done.

so even if she's a bit unsure, suspicious, she decides to trust dave. even if this was way too easy, leaving a bad taste in her mouth. later she might realize why, possibly while in a pumpkin patch with karkat. but for now she looks between dave and karkat again, waiting to see if something suddenly implodes like it feels it should. when it doesn't, rose nods resolutely. ]

No, I suppose that's it. You two can work out any details yourselves without my meddle-- mediating, yes? Is there anything else needing discussion?

[ that question is directed at karkat, since he isn't the discussion avoider in the room. ]
