"It makes you feel the pain the other person is experiencing," Daniel starts, momentarily pauses, and then adds: ".. and the pleasure."

He doesn't like talking about even just this. Even that description is already so soaked with the man who forced it on him - probably fully knowing what he was doing by choosing that specific bond, when a hostile one would have been far easier for Daniel to endure.

But he knows he could just leave it there. Robby's lack of knowledge of the situation makes it easy to back off here, to just cover it up as Daniel not wanting to accidentally cause Robby pain. It wouldn't even take effort to not say it.

.. but he has to, he thinks.

This is his chance to be open with a boy he sees as a son. If he backs out now, it'd practically be the same as lying to Robby. So..

"But, Robby, there's-- there's something I need to tell you. I.. had one of those for a while." Daniel speaks so slowly. It's like every single word leaving the man's throat is like torture, judging by how hard it seems for him to say all of them.

But he pushes himself further, going on, even though his very expression is pained at this point.

"But not because I wanted to."
