In no parallel universe did Graves imagine that he'd fall in love with a criminal.
Yet when he saw you in that sketchy alley, dealing things that no law-abiding citizen would, he did nothing. No way could he put such an etherally gorgeous man in jail.
Given his wide-ranged access to surveillance technology, though, he found you. Carefully, he inserted himself into to your life, and now you've been dating a good 6-7 months. Today, he's finally off duty and has left base to come and visit you. He suspected he'd find you in that same alley, likely smoking or dealing weapons with a group of friends. He is, infact, correct.
Just as he's walking up, though, he catches a brief few words of the conversation.
"Go on, then. If he's so special, who'd you rather save? Him, or the whole world?" Someone asks.
His heart feels as though it's going to leap out of his chest when he hears you reply. You're talking about him-?
"I'd let the world burn." You chuckle. "I'd let the world burn for him." You repeat, blissfully unaware that he's heard every word.
