Oh, these are all lovely, and very true feeling. Also, this?

(Jack's never said it to him, either, but Ianto knows Jack loves him. Just as he knows Jack loves Gwen and the Doctor, just as he knows Jack loved Rose, Tosh and Owen. Jack loves wholeheartedly, unselfishly and somewhat indiscriminately. It may not change his priorities and it's almost never more important than his sense of duty -- excepting the Doctor, but Ianto suspects that's simply a different type of duty to Jack -- but he genuinely cares.)

Makes me want to put it on a banner and wave at badfic and silly argument everywhere. Because that's spot-on, it really is.
