I went and read Fealty right after I finished ep 13! XD I'd been saving it until after I watched the mid-season arc. And yesss, it was fantastic (So was her 'Bargain at the Price', my goodness. *fans self*). I think their relationship appeals to me for a lot of the same reasons I like Clint/Coulson so much - there's that sort of handler/operative dynamic between them, with the ensuing mashing of my trust!kink buttons. <3
