Just image how hard it kills Cullen inside not to be able to go with the Inquisitor to fight the final battle, that he isn’t there with his shield & his sword to defend them, protect their back, to give his life for them if need be. Whatever it takes to make sure they back alive. That he’s left watching from afar, unable to act, to do anything. Suddenly he’s back all those years ago, helpless again, to stop or change what is to come. This time it’s worse, because it’s not just a fellow soldier or an nameless innocent, no he knows this face, knows their name & voice & laughter, how they sound when they wake up beside him, remembers their smile & how their lips feel, how their hands fit perfectly between his own. He knows this person better than any other & what they make him feel like for the first time in his life. He doesn’t want to let it go, doesn’t want to let them go. He can’t.
