"We've never had a normal bond, that's part of it. How I felt has always been what you knew between us." The fact that Istredd had it bad for him was why they ended up here. Too close. Too intertwined with one another. He probably should feel bad about it since like he told Lucifer before, he didn't really know what he was signing up for.

I told you when we did it that it was just for communication and I'd avoid emotional bleed as much as possible. An appropriate bond would be more like.... Istredd pulls back and builds a wall of a kind between them. As he once described, they can feel the bond there, it would be easy to reach out to communicate or connect in an emergency, but none of his emotions are felt now. It's more like a polite handshake than the mental equivalent of what they're doing in bed now, on top of each other.

Showing it probably puts into view how much Istredd messed up what he was supposed to do. Lucifer warned him about his anger bleed and that was not what happened. He drops that block. Sorry. I really was the screw up this time. Istredd is a little sorry but not a lot.
