Whether Dirk realizes it or not, Ranboo can feel the way he's tensing against him, the physical recoil from Ranboo's own reaction, and it makes them feel bad. There's a whole lot to unpack here, but... the only thing that Ranboo can say for sure right off the bat is that whatever Dirk's brothers did to him wasn't his fault.

"S... sorry, I just--" So... so that's where Dirk learned the things that he likes. From... that. And... he's had Ranboo reenact those same things? Something akin to shame washes over Ranboo for having done those things, for having even unintentionally echoed such acts-- and beneath that, there's an alarm, a discomfort.

"You told me to... do things-- that-- that they did to you?" You liked it? Ranboo isn't sure what to say or feel. Why would Dirk do that in the first place? Wouldn't he want to forget about those things? Wouldn't he never want to think about them again?

"Why?"
