I’m convinced the sighting of DD on the set of the Fall proves they are/we’re together at some point. I don’t care how good of friends you are with someone, you don’t cross an ocean to go hang out on a set. He has his own responsibilities. Been around a year in this fandom but for me, this is all the proof I’ve needed. And I’m soooooooo jealous of Gillian. God I would give my right arm for one of them to spill all in a memoir.
