"I might have." There's no guarantee. Istredd might have stopped learning it once he did get back and got used to normal life again. He's a very stubborn person and he gets tunnel vision, as Lucifer knows very well by now. He is no longer being pinned to the wall so he relaxes. He doesn't immediately cross his arms in a defensive posture or come back with another argument.

"At least you would have been able to say I told you so for the next eight hundred years." He reaches out to snag Lucifer's shirt cuff. Not his arm or his hand, out of respect that he's still in trouble over this, but for a point of contact somewhere, his fingers trailing the fabric.

"I'm sorry. I know I make it difficult." Istredd never apologizes unless he means it, mostly because he likes to stand by his argument for being right instead. But in this case, he's gotten enough people yelling at him from all sides to know he wasn't at his best. "I thought it was the right thing."
