For all that I adore all the Ewen/Keith stuff, as a teenager my absolute favourite bit of the entire book was the bit where Ewen throws himself in front of the cannon fragment to protect Lochiel, and comes round to find himself cradled in Lochiel's arms. It is just SO dramatic and perfect, Ewen is so happy to have the chance to die for Lochiel, and the bit where his first reaction is to check that Lochiel's okay... I don't ship it, but I do adore it as the absolute pure form of platonic loyalty kink. And of course it sets up just how happy Ewen would be to die for Lochiel, to give meaning to what happens later on.
