It makes a difference. To have value in himself. Lucifer himself struggles with that so it's hardly surprising, but Lucifer is aware that despite those struggles, he knows his absence would have an impact on others. Maybe it can't completely be enough, but the answer does matter.

I'm sorry, and that is packed with a shaking level of sincerity for someone that has only done this sort of thing twice now, that I didn't message you back that last time. That's been in some back part of his mind, the part still feeling Istredd's sacrifice, looped and tied together.

He backs up and pulls Istredd with him, sinking to sit on the bed and pull Istredd down to him. It isn't so much Lucifer getting accustomed and more comfortable with touch as it is recognizing their boundaries and allowances and being allowed to partake in something he never could and letting himself have it.

"I thought the last thing--" I thought the last thing I'd ever say to you was 'well you probably can't make it any worse' and that--wasn't fair to you, either.
