This was lovely. I think Dafydd is having his own "Aha" moment -- realizing that Ianto is all grown up. Can be hard sometimes especially if he consistently refers to Ianto as "his little brother". I actually resented Dafydd in the series, and, now, reading his perspective, I still am peeved at him, but understand him a little better - placing yourself in someone else's shoes and all that. Maybe you have to see people objectively in order to really know them -- leave out your prejudices and preconceived notions. And Dafydd is really getting and eyeful and earful in this story. But, I am glad he finally does see his brother in a new light and that he is proud of him, and I especially like that he worries about Jack as well. "Aha" moment indeed. Well done.
