I considered it, and then decided it was a stupid fucking idea to try to limit the amount of time spent hugging when Dave and Roxy are both natural clingers. [Also Dirk likes hugs? Pretty much everyone in this family has suffered from Not Enough Hugging and Dirk is perfectly willing to put his coolkid persona in the trash to rectify this mistake.]

I know you aren't cool with PDA. It's why I'm suggesting a room attached to ours. You'll be nearby, but you'll have privacy when we get to be a bit much. There are shutters and no cameras built in. Not even URSULA will be able to see you in that room.

[She... might be able to hear him, he doesn't know, but he definitely ensured that there would be visual privacy. That swim-by witnessing is something that he imagines Karkat would not want to repeat. If he knew about it.]
